Abstract

Fe^{3+} doped CdS nanoparticles using Mercaptoethanol as a capping agent were prepared by colloidal wet-chemical method. UV-VIS spectra show that Fe-doping can effectively tune energy band structure, i.e. a large blue shift (\sim 30 nm) with increasing Fe concentration. PL measurement of doped CdS nanoparticles shows an additional emission band at \sim 532 nm, which can be due to radiative transition of dopant level to ground state. X-ray diffraction patterns studies revealed cubic crystal phase. TEM micrographs show a spherical shape and nearly well distribution with an average particle size of \sim 4 nm.
