Abstract
The paper gives a keen insight of thermal and optical characteristics of rare earth impurities doped metazirconate perovskites synthesized by low temperature salt melt technique. The impurity concentration of each rare earth doping ions varies from 0 mol% to 2 mol%. The synthesized perovskites when subjected to crystallographic, morphological, topographical optical and thermal analyses, many interesting characteristics were revealed. The structural analysis confirms the crystalline nature of synthesized perovskites with homogeneity and phase purity. The topographical and morphological studies show formation of particles with distinct morphology, variable shapes and sizes agglomerated into clusters. The thermal analysis indicates the thermal stability of synthesized perovskites with less weight loss%. The study of thermoluminescent (TL) behavior of synthesized perovskite phosphors set forth the second order kinetics, deep trapping mechanism and high value of activation energy exhibited by these phosphors.
