Synthesis and Optical Behavior of Rare Earth Doped Calcium Zirconate Perovskite Phosphors
Abstract
The single perovskites activated with trivalent rare earth impurities show drastic enhancement of their optical,
electrical, thermal and magnetic characteristics. With distinctly amended properties, rare earth doped calcium zirconate
(CZO) perovskites are emerging as promising competent for future research and applications. This investigation reports the
enhanced optical characteristics of Eu3+ doped and Tb3+ co-doped CZO perovskites. Samples with Eu3+ 1 mole% and Tb3+
(0.5-2 mole%) were synthesized by Solid State Synthesis route. The phosphors show orthorhombic structure with an average
crystallite size of 29.44 nm in PXRD analysis. The SEM morphological studies confirm agglomerated and uniformly
connected grain distribution in the prepared samples. Characterized by FTIR for functional group analysis, a detailed
investigation of molecular activities of synthesized phosphors was done. In the PL spectroscopic analysis, the phosphor
gives variable emission in spectral region. An imperative investigation of structural and optical characteristics of synthesized
phosphor is done for future display device applications.
