Abstract:Mercury Cadmium Telluride (MCT) nanoparticles were synthesized by Solvothermal method for the first time. Mercury, Cadmium and Tellurium in compound/elemental form were added to Ethylenediamine (solvent) in the Teflon-Stainless-Steel autoclave along with a reducing agent. Different compositions of MCT were synthesized by varying the proportions of Hg and Cd to obtain Hg1-xCdxTe with x varying from 1 to 0. X-ray diffraction patterns revealed the formation of MCT nanoparticles with predominant cubic (111) phase. TEM studies revealed that the average particle size ranged from 10 to15 nm for different compositions.
