Structural, Thermal and Optical Studies of Bismuth Doped Multicomponent Tellurite Glass

Abstract

In this communication, structural, thermal and optical absorption properties of bismuth doped multicomponent tellurite glass (69TeO2-10ZnO-10WO3-5Na2O-5TiO2-1.0Bi2O3 (mol %)) synthesized using melt quench method is reported. The X-ray diffraction confirms the amorphous structure of the synthesized glass. IR spectrum of bismuth doped glass show band at 601 cm-1. Raman analysis observed mainly in four spectral regions which are R1 (65-150) cm-1, R2 (280-550) cm-1, R3 (880-950) cm-1 and R4 (916-926) cm-1 and identified bands are assigned to respective molecular groups. Thermogravimetric analysis profile show stability regarding to weight loss. Differential scanning calorimetry indicates good thermal stability of the synthesized glass for its applications in optical fibers. The absorption spectrum identified the cutoff wavelength at 430 nm.

Review—Recent Advances in Bismuth Tellurite Glasses for Photonic and Radiation Shielding Applications

“…The findings from the CW-SPM method suggest that the Bi 2 O 3 -modified glass fiber investigated in the study could be a favorable option for use in nonlinear optical material applications like amplifiers, Q-switching elements etc. Kawa et al 66 investigated the structural, thermal, and optical absorption properties of bismuth-doped tellurite glass with a composition of 69TeO 2 −10ZnO-10WO 3 −5Na 2 O-5TiO 2 −1.0Bi 2 O 3 . The IR spectrum of the glass revealed a band at 601 cm −1 due to bismuth doping.…”

DC Conductivity of Heavy Metal Oxide (Bi2O3) Boro-Tellurite Glasses: Effect of Eu2O3

“…But tellurite based glasses show good chemical durability, low melting point, better optical properties, and good mechanical strengths. Glass forming ability of TeO2 can be enhanced by adding other glass formers, and among all available glass formers, boron oxide is well suited to TeO2 due to its low melting, high thermal stability, and high glass-forming ability even with regular quenching rates [24][25][26][27][28]. Additionally, TeO2-based glasses [12,13], unlike the transition metal ions (TMI), have been measured to have higher electrical conductivity than silicate, phosphate, and borate samples.…”
