A METHOD FOR PREPARING MAGNETO OPTICAL GLASS COMPRISING BI2TE3 NANOCRYSTALS

摘要

A method for developing magneto optical glass comprising Bi2Te3 nanocrystals has been disclosed. The method includes the steps of mixing SiO2, Na20, K2O, ZnO, of B2O3, TiO2 and MgO at pre-determined quantities, to obtain a host glass mixture, adding 0.5% - 0.7% of Bi2Te3 as dopant to the said host glass mixture, heating the host glass mixture at a temperature ranging between 1250°Cand 1400°C, soaking said host glass mixture and obtaining a melt of the host glass mixture, quenching said melt in air up to the stage of transition of the melt into Bi2Te3 glass nanocomposite, annealing Bi2Te3 glass nano composite, at a pre-determined temperature, and subjecting annealed Bi2Te3 glass nanocomposite to a temperature proximate to the transition temperature of the Bi2Te3 glass nanocomposite and stimulating the formation of Bi2Te3 crystals in said glass nanocomposite.
