Abstract

This lecture intends to present recent results on design and development of molecular precursors for the synthesis of some binary and ternary compound semiconductor nanoparticles. A wide variety of complexes of Group II, III, IV and V elements with dithiocarboxylate, xanthate, dithiocarbamate, selenocarboxylate and N,N-dimethylaminoalkylchalcogenolates have been prepared and characterized by spectroscopic and single crystal X-ray diffraction techniques. Several of these complexes on thermolysis yield bulk as well as nanoparticles of metal chalcogenides (ME : M = Zn, Cd, Hg, Pb; E = S, Se, Te) and M 2 S 3 (M = In, Sb, Bi)). The latter have been characterized by XRD, EDAX, SEM, TEM, SAED and photoluminescence.
