Bismuth borate glasses doped with cerium in the composition 50Bi2O3:(50-x)B2O3:xCeF3 were prepared for the composition range 0x2.5 (in mol%). The glass samples have been fabricated by the conventional melt quenching technique. The physical and optical properties of glass samples were investigated. The optical absorption spectra of the glasses have been measured in the wavelength range 190-1100 nm and no absorption peak was obtained in this region. The absorption spectra of all samples were shifted to longer wavelength with increasing of CeF3 concentrations. Optical band gap decreased and refractive index increased with increasing of CeF3 concentrations.

Work Effect

In this work, effect of Li2O and Na2O on bismuth borate glasses have been investigated. The glass samples were prepared in composition 44B2O3 : 50Bi2O3 : 5Li2O : 1A2O3 and 44B2O3 : 50Bi2O3 : 5Na2O3 : 1A2O3 (where A2O3= Sm2O3 and Dy2O3).Glasses were prepared using the melt-quenching technique at 1,100 oc under normal atmosphere. The result found that, the density and molar volume of lithium bismuth borate glasses are less than sodium bismuth borate glasses both in Sm2O3 and Dy2O3. In addition, the optical absorption spectra and luminescence of lithium bismuth borate glasses are higher than sodium bismuth borate glasses both in Sm2O3 and Dy2O3.

Bismuth Borate Glass

Ho3+ doped zinc bismuth borate glasses of the composition 10ZnO : 30Bi2O3 : (60-x)B2O3 : xHo2O3 (where x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol%) were fabricated by conventional melt quenching technique. In order to understand the role of Ho2O3 in these glasses, the density, molar volume and optical spectra were investigated. The molar volume decreases with an increase in Ho2O3 content, which is attributed to the structure becomes more compacted. The absorption spectra of Ho3+ doped in zinc bismuth borate glass correspond to several bands, which are assigned from the ground state, 5I8 to 5G5 (420 nm), 5G6 + 5F1 (451 nm), 5F2 + 5F4 (538 nm), 5F5 (643 nm) and 5I5 (1152 nm). Moreover, the optical basicities were also theoretically determined.

In this study, the effect of zinc bismuth borate (ZBB) glass and bismuth borate glass (BB) doped with trivalent dysprosium ion were investigated. Glass were prepared by the conventional melt quenching technique, with the chemical composition of (60-x) B2O3: 30Bi2O3: 10ZnO: xDy2O3 and (70-x) B2O3: 30Bi2O3: xDy2O3 where x = 1.0 mol %. The results show the densities of glasses are 3.91 g/cm3(ZBB) and 4.24 g/cm3 (BB), respectively. The absorption spectra consists of six absorption bands that are located at 752, 796, 902, 1096, 1276 and 1681 nm, and are assigned to 6H15/2 to 6F3/2,6F5/2, 6F7/2, 6H7/2+6F9/2, 6F11/2+6H9/2 and 6H11/2 transitions. The emission spectra exhibited three emission bands corresponding to the 4F9/2 → 6H15/2 (483 nm; blue), 4F9/2 → 6H13/2 (575 nm; yellow) and 4F9/2 → 6H11/2 (664 nm; red) transitions. The lifetime for 4F9/2 → 6H13/2 transition are 0.178 ms (ZBB) and 0.420 ms (BB). Both of Dy3+ in ZBB and BB glasses have been show white emission and illustrated by CIE 1931 chromaticity coordinates.

Neonymium doped bismuth borate glasses with composition 50Bi2O3 : (50-x)B2O3: xNd2O3 (where x = 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) have been prepared by melt quenching technique. The optical and upconversion luminescence properties of glasses were investigated. The nine absorption peaks were observed, correspond with Nd3+ energy level in glass. The optical band gap decreased with increasing Nd2O3 concentration due to the increase of non-bridging oxygen (NBOs) in glass matrix. The upconversion luminescence emission spectra shows peak at 393 nm, assign to 4D3/24I11/2 transition.

Bismuth titanium borate glasses in compositions xTiO2 : (30-x)Bi2O3 : 70B2O3 (with x is in mol%, varying from 0% to 10%) were fabricated by the conventional melt quenching technique. The effect of TiO2 on the physical and spectroscopic properties of bismuth borate glasses have been carried out by means of density and UV-Visible spectroscopy measurement techniques. The density and molar volume of all glasses are found to change depend on TiO2 substitution. The fundamental absorption edges for all glasses have been identified using the theory proposed by Davis and Mott. The optical band gap (Eg) is found to decrease with increase in TiO2 content.
