Microwave-solvothermal synthesis of nanocrystalline cadmium sulfide

The microwave assisted synthesis is generally much faster, cleaner and more economical than the conventional methods. The combination of microwave and hydrothermal techniques has been used Ill the last few years for the synth esis of nanocrystalline powders. We present here a versatile process of nov el microwave-solvothermal technique for synthesizing nanocrystalline CdS pa rticles. The effect of different parameters such as time, temperature, solv ents and molar ratio of Cd2+ to thiourea on the phase(s) formation of nanoc rystalline cadmium sulfide under micrawave-solvothermal conditions using mi crowaves of 2.45 GHz frequency are investigated. The obtained CdS is charac terized by the powder X-ray diffraction and SEM. (C) 2001 Elsevier Science B.V. All rights reserved.
