Optical and thermal characterization of Nd3+doped Ce2 (C2O4) 3 10H2O crystals
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 3
Abstract
Optical And Thermal Properties Of The Neodymium (Activator) Doped Cerium (Sensitizer) Oxalate Single Crystals Grown By Hydrosilica Gel Method Were Studied At Room Temperature. The Crystals Are Bright, Transparent And Light Pink Coloured. The Emission And Absorption Spectra Of The Crystals Are Recorded And The Peaks Of The Impurity And The Host Crystals Are Identified. From The Absorption Spectra Oscillator Strengths Of This System Are Evaluated By Least Square Programming. The Emission Peak Intensities Of Cerium Decrease While That Of Nd Increases For 230 Nm-Wavelength Excitation, Which Confirms The Energy Transfer Mechanism. Ftir Spectra Show The Presence Of Water Molecules And The Number Was Measured From The Thermal Analysis.
