XRD, UV-VIS, PL and Thermal Studies of Lead Iodate Crystals

Abstract

The lead iodate crystals have been grown in sodium meta-silicate gel using the single diffusion method at room temperature. The grown crystals were characterized by X-ray powder diffraction (XRD), UV, PL, and TGA/DSC. The crystal system is confirmed to be orthorhombic, having lattice parameters a= 16.70Å, b= 5.578Å and c= 6.083Å by powder X-ray diffraction analysis. The crystal's optical properties were characterized using UV-visible and Photoluminescence (PL) spectroscopy. TGA and DTA/DSC analysis show remarkable thermal stability.
