Synthesis,characterization and investigation on optical properties of sodium cerium double tungstate [nace(wo4)2] nanomaterials

Abstract

The study given in the thesis “Synthesis, Characterization and Investigation on Optical Properties of Sodium Cerium Double Tungstate [NaCe(WO4)2] Nanomaterials” is primarily concerned with two segment: first, the synthesis of scheelite material NaCe(WO4)2 and second finding the changes in optical properties. Rare earth oxide materials have potential applications in optoelectronics owing to their unique optical properties that arise from 4f–5d electronic transitions. Optical properties such as Photoluminescence (PL) of these oxide materials are found to be determined by their crystallographic features as well as type of activator ion and sensitizer ion residing in the host lattice. Alkali rare earth double tungstate with the general formula ARE(WO4)2, where A is an alkali metal ion, RE is a rare earth ion, and M = W/Mo, were known to adopt the Scheelite-like crystal structure. These materials have received a lot of interest owing to their structural stability and tenable optical properties. The primary goal is to synthesize NaCe(WO4)2 using Hydrothermal Method. Their structural and optical properties have been researched and characterized. The control of its size and form was achieved by adjusting the preparation parameter.
