Synthesis of some optical materials by sol-gel technique and their structural characterization

Abstract

The present research work deals with synthesis of Y₂O₃:SiO₂ and Gd₂O₃:SiO₂ nanocomposites around moderate annealing temperature and their optical properties were also investigated. Monitoring of shape, size, crystallinity and densification of the samples were demonstrated by multi-step annealing schedule. Precursors were refluxed by using sol-gel technique and dried samples were sintered at different temperatures and incubated for few hours. The main objectives of this thesis are to demonstrate the synthesis and phase evolution of the prepared binary oxides.
