“…Tellurite glass is primarily composed of TeO2 [6], which possesses a unique set of properties. Although the addition of other components is necessary for glass formation [7], tellurite glass exhibits a low melting point, excellent thermal stability, high density, a high refractive index, low energy phonons, and remarkable chemical and physical resistance [8][9][10][11][12].…”

New tellurite glasses having compositions: 60TeO2-(35-x)ZnO-3Bi2O3-2Na2O-x PbO and 55TeO2-(41-x)ZnO-2Bi2O3-2Na2O-x PbO where x = 0 and 0.5 mol% were fabricated and characterised in order to study the effect of substitution of PbO by ZnO. Density measurement was carried out by applying Archimides principle, that is by using pycnometer. Refractive index measurement was carried out by applying Brewster angle method, at which the intensity change in transversed magnetic light (λ = 632.5 nm) was recorded. From the experiment it can be shown that the glass density increses with the increse of PbO concentration, for the first glasses it change from 5.71 to 5.74 gr/cm3 while for the later it change from 5.85 to 5.87 cm3. Their molar volumes, however, behave inversely. Refractive index change due to this compostional change behave in same manner as density, refractive index increses with the increase of PbO content. Refractive indexes of the first pair are 1.89 and 1.93, respectively, while the later are 1.88 and 1.95, rspetively. Based on these findings, each pairs is a potential candidate for fabricating fiber optic at which the lower index is for cladding material while the higher index for core material.
