The Difference

The borosilicate glass samples doped with NiO have been fabricated by conventional glass making process and changed the composition of chemicals. Rice husk ash (RHA) was used as a SiO2 source for prepare the glass samples. The physical and optical properties, viz., glass density, molar volume, refractive index and absorption spectra have been studied. The results show the density increased with increasing of NiO amount due to the difference of atomic weight of Si and Ni. The molar volume obtained from the density of glass, depends on changed rates of density and atomic weight. Those values increased when the amount of NiO increase due to the increasing in bond length between atoms. Moreover, the refractive index increased with increasing concentration of NiO.

Optical And Mechanical Properties

In this paper, the optical and mechanical properties of injection-moulded plates (thickness: 1 mm) made of poly(methyl methacrylate) (PMMA) and glass particles as filler with a matching refractive index are investigated. Tests show that the orientation resulting from the injection moulding process greatly affects the tensile strength and elongation at break, whereas the elastic modulus merely depends on the filling degree, which is investigated up to 13 vol.%. In terms of the optical properties, the specimens’ haze depends on the difference in the refractive index between a glass and polymer. However, the absolute value of haze increases with increasing filling degree and decreasing particle size. Surface defects resulting from the injection moulding process were found to be the primary reason for this haze, even with identical RI between PMMA and glass.

Modifying the optical properties of rare earth doped phosphate glasses in a tunable fashion via the embedment of magnetic nanoparticles (NPs) is challenging for magneto-optic devices. Glasses with compositions (69-x)P2O5-30ZnO-1Er2O3-(x)Fe3O4, where x = 0 to 1.5 mol% are prepared by conventional melt quenching method. The Fe3O4NPs concentration dependent density, molar volume, refractive index and optical properties are determined. Density and molar volume shows strong correlation with structural alteration in the presence of NPs. The XRD spectra confirm the disordered nature of the glass and TEM micrograph display the presence of spherical NPs with average size ~26 nm. The optical band gap and Urbach energy calculated from the room temperature absorption spectra recorded in the range of 350-1700 nm reveal significant improvement. The density and refractive index increases and the molar volume decreases with the increase of Fe3O4contents. The energy band gap for direct and indirect transitions varies in the range of 4.47-3.64 eV and 4.27-3.53 eV, respectively. The Urbach energy increases from 0.15 to 0.19 eV as the NPs concentration increases from 0 to 1.5 mol%.

This study aims to determine the optical and physical properties of TZBN:Nd glass with the composition (mol%) 60TeO2-2Bi2O3-(34-x)ZnO-4Na2O-xNd2O3 with variation of doping x = 0.5; 1.0; 1.5; 2.0. Fabrication has been done by using the melt-quenching technique. Characterization of tellurite glass covering density, refractive index and absorption spectrum of glass. Density of glass have been measured using the Archimedes method. Refractive index of glass have been measured using the Brewster angle at wavelength 746.191 nm. Absorption spectrum measurements using UV-Vis-NIR spectrophotometer Perkin Elmer Lambda 25 in the region of 200-1100 nm. The results of characterization show that density / physical characteristics of glass did not increase when the concentration of ions Nd3+ to TZBN:Nd glass increased. The refractive index of glass will increase as the concentration of ions Nd3+ to TZBN:Nd glass increased. Based on the results of UV-Vis-NIR spectroscopy measurements shows that there are nine significant spectra have been observed in the region of 200-1100 nm, such as at a wavelength of 431 nm, 474 nm, 515 nm, 527 nm, 585 nm, 684 nm, 749 nm, 805 nm, and 878 nm and the highest absorption peak is at a wavelength of 585 nm.

This research reports on the physical and optical properties of three series of borophosphate glasses combined with barium oxide (BaO), following BaBP-A, BaBP-B and BaBP-C, that were prepared by a melting and quenching process. The density, molar volume, refractive index and absorption spectra were investigated the effect of BaO on different glass structures. The results show that the densities and refractive index of the glass samples increased as the BaO (BaBP-A and BaBP-B) and B2O3 (BaBP-C) mole percentage increased. The molar volume of the glasses shows the adversative trend as the density: the molar volume decreased as the BaO and B2O3 content increased. The absorption spectra of all glass samples were slightly shifted to the longer wavelength, ultraviolet 250-350 nm, with increasing the concentration of BaO.

In this work, the glass samples were prepared from the rice husk ash (RHA) with different PbO concentrations by melt-quenching technique. The effect of PbO on the physical and optical properties of the glasses from RHA have been studied. The results showed that the refractive index and density increased with increasing PbO concentration. The absorption spectra of all samples showed the cut-off wavelength approximately at 360 nm. For comparison, similar properties of SiO2 glass doped with different PbO concentrations were also studied. It was found that the RHA is possible to be used as a raw material in the glass production.

The alkyl or alkanol amines are widely used as absorbent for CO2 capture owing to interaction between amines and CO2. In order to increase the CO2 loading in amine based absorbents, blending of amine with alkanol may be one option. As thermophysical properties of of utmost importance in designing, in present work, the refractive index of dibutylamine (DBA) and isomeric butanol as well as their binary mixtures at 298.15 K to 308.15 K were measured. The Δn are found positive for DBA + isomeric butanol mixtures. The Δn values were correlated with Redlich-Kister polynomial. The refractive index data were also predicted by various correlations and results were expressed in terms of standard deviation. The Δn values were also employed to calculate the excess molar volume of the present binary mixtures. Further Δn data analysed in terms of intermolecular interaction among DBA (1) + isomeric butanol (2) mixtures.

The Difference

Recently, White light emitting diodes (WLEDs) have been studied because of many advantages such as lower energy consumption, fast response, high brightness. Glass frit has been interested in LED packages due to their superior properties such as long-term stability and permeability. To maximize the LED light emission characteristic, the glass frit was required a low firing temperature and high refractive index. We selected the bismuth-based glass due to their low melting and high refractive index. This study was investigated characteristics of glass according to the influence of the glass within Bi2O3 content and this glass characteristic change was studied the effects on the optical properties of LED package structure. The properties changes of the glass frit affect the optical property of the mixed paste. With higher contents of Bi2O3 glass composition, the transmittance and emission intensity of the mixed paste was increased. These results suggest that the difference in refractive index between the phosphor and glass frit is minimized, the loss of light is minimized.
