Research abstract
IN PHASE I, A SYSTEMATIC AND COMPLETE INVESTIGATION ON THE SYNTHESIS OF CADMIUM SULFIDE WILL BE CONDUCTED. CADMIUM SULFIDE (CDS) WILL BE SYNTHESIZED BY TWO METHODS: 1. SPONTANEOUS REACTION BETWEEN DIMETHYLCADMIUM AND HYDROGEN SULFIDE, AND 2. REACTION OF CADMIUM AND SULFUR ELEMENTS BY VAPOR DEPOSITION. THE CDS POWDER OBTAINED FROM THESE TWO TECHNIQUES WILL BE HEAT-TREATED BY BAKING OUT AT ELEVATED TEMPERATURES UNDER VACUUM CONDITION TO ADJUST ITS STOICHIOMETRY. VARIOUS ANALYSES, INCLUDING ATOMIC ABSORPTION SPECTROSCOPY, SPARK SOURCE MASS SPECTROSCOPY AND ENERGY DISPERSION OF X-RAY ANALYSIS, WILL BE PERFORMED ON EACH BATCH OF CDS TO CHARACTERIZE THE PURITY AND STOICHIOMETRY. THE OPTIMAL SYNTHESIS PARAMETERS WILL BE ESTABLISHED.
