Abstract
Amorphous and crystalline powder of PLZ was prepared by using the polymeric precursor method. TGA-DSC (Thermal analysis and Differential Scanning Calorimetry) shows the decomposition of polymeric resin, an amorphous phase and the crystallization of powder. Raman scattering of powder shows an amorphous and semicrystalline phase at 450 and 550 °C, respectively. XRD (X-ray diffraction pattern) of powder shows high crystallinity at 700 °C/3 h. PL (Photoluminescence) analysis of powder at 300 °C/3 h shows a broad asymmetric peak at 585 nm and increases of calcining time led to intense peaks of PL at 300 °C/6 h. This emission could be attributed to Zr → O from the oxygen-2p orbitals to the zirconate-3d orbitals.
