Abstract

We have investigated the synthesis of nanostructured CuInS₂ (CIS) with using a microwave method. Dark brown CuInS₂ nanopartieles were obtained by mierowaving the mixture of InCl₃, Cu (gly)₂ as a novel precursor and S (Thiourea) in 1:1:2 stoichiometric ratio in propylene glycol for 12 min. These nanoparticles were characterized extensively by techniques like powder X-ray diffraction, Room temperature photoluminescence (PL) spectroscopy and Fourier transform infrared (FT-IR) spectra. The absorption and photoluminescence studies of the CuInS2 nanoparticles displayed quantum confinement behavior. An XRD study showed a tetragonal structure for CuInS₂ prepared by microwave method. The band gap for CuInS₂ was 2.2eV.
