Physical and optical properties of mixed Mn-Co ions in soda lime silicate glasses were measured and calculated. The results show that, the densities increased with the increasing of CoO content. This indicates that increasing the molecular weight of oxide ions used in the glass was due to the replacing SiO2 by CoO. The refractive indices were increased with increasing of CoO concentration. The absorption peaks of CoO doped glasses occurred at the wavelength around 511, 584 and 649 nm which are assigned to 4A2(F) ® 2A1(G), 4A2(F) ® 4T1(P) and 4A2(F) ® 2E(G) transition, respectively.

Soda Lime Silicate Glass

Soda-lime-silicate glasses in the compositions of (65-x)SiO2-25Na2O-10CaO-xHo2O3 (where x = 0.0, 0.50, 1.00, 1.50, 2.00 and 2.50 mol % ) were prepared by melt-quenching technique and characterized. The results show that, the absorption spectra of Ho3+ doped in soda-lime-silicate glass correspond with several bands, which are assigned from the ground state, 5I8 to 3H6 (360 nm), 5G4 (380 nm), 5G5 (417 nm), 5G6 (453 nm), 5F3 (479 nm), 5F4 (538 nm), 5F5 (639 nm), and 5I5 (880 nm). The refractive index and density of glasses were increase with increasing of Ho2O3 concentration. The color of glass samples is light amber with doped Ho2O3 in glass matrix.

In order to study the surfactant-free emulsion copolymerization of benzyl methacrylate (BMA) with sodium 1-allyloxy-2-hydroxypropane sulfonate (COPS-I) and the resulting optical properties, a series of experiments was carried out at various reaction conditions such as the changes of BMA concentration, COPS-I concentration, BMA concentration under a fixed COPS-I amount, initiator and divinyl benzene (DVB) concentration. All the latices showed highly monodispersed spherical particles in the size range of 144∼435 nm and the respective shiny structural colors from their colloidal photonic crystals. It is found that the changes in such polymerization factors greatly affect the number of particles and particle diameter, polymerization rate, molecular weight, zeta-potential, and refractive indices. The increase of number of particles led to the increased rate of polymerization and zeta-potential of the latices, on the other hand, to the decreased molecular weight. Refractive indices and the reflectivity increased with COPS-I concentration, on the other hand, and decreased with DVB concentration. Especially, refractive indices of the resulting poly[BMA-co-(COPS-I)] colloidal photonic crystals showed much higher values of 1.65∼2.21 than that of polystyrene, due to the formation of core–shell shaped morphology. Monodisperse and high refractive index of poly[BMA-co-(COPS-I)] particles prepared in this work could be used for the study in photonic crystals and electrophoretic display.

Series of multi-component glass systems of the following chemical composition SiO2-Na2O-CaO-Nd2O3 with an increasing of rare earth concentration, the effect of Nd2O3 on the optical properties of the glass systems is investigated. On the basis of the measure values of densities and refraction, Nd3+ ion concentration in glasses and several other physical properties were determined. The absorption coefficient, both direct and indirect optical energy gaps, and Urbach energy are evaluated using the absorption edge calculations. The different factors that play a role for controlling the refractive indices such as electronic polarizability, bridging and non-bridging oxygen, and optical basicity are discussed in accordance with the obtained index data. The non-crystalline phase identified basing on X-ray diffraction analysis.

In this work, effects of Ni2+ ions on soda lime silicate glasses have been investigated. Glasses were prepared in formula (65-x)SiO2 : 25Na2O : 10CaO: xNiO (where x is 0.00, 0.02, 0.04, 0.06, 0.08 and 0.10 mol%). The densities of glasses not depend on Ni2+ concentration. The refractive indices decreased with increasing of NiO concentration. The optical absorption spectra were measured by uv-visible spectrophotometer and show peaks correspond with Ni2+ in glass matrices. Both of octahedral transitions and tetrahedral transition from Ni2+ ion were found around 450 and 625 nm respectively. The color of glasses were also measured in CIE L* a* b* system.
