Effect of Sample Preparation Route on the Thermal Diffusivity of Nd2O3 - A Laser Induced Photoacoustic Study

Abstract

Knowledge of thermal and optical properties of rare earth oxides is important in the context of optoelectronic component and device development. The method of preparation of a sample has profound effect on its physical as well as chemical properties. In the present work Nd2O3 is prepared by two different methods such as oxalate and hydroxide methods. The thermal diffusivity of these differently Nd2O3 samples are determined by laser induced photoacoustic technique. The method is standardised by determining the thermal diffusivity of copper. The effect of method of preparation on thermal diffusivity of Nd2O3 is studied.
