Title: Synthesis and investigation of optical properties of TOPO-capped CuInS{sub 2} semiconductor nanocrystal in the presence of different solvent

Graphical abstract: - Highlights: • TOPO-capped CuInS{sub 2} nanoparticles were synthesized by injection method. • Pure CuInS{sub 2} nanoparticle was obtained by injection in 200 °C. • The size, shape and optical properties of products were controlled. • Nanoparticles with size smaller than 10 nm and wurtzite phase was obtained. • The absorption and PL spectra of CuInS{sub 2} nanoparticles were tunable. - Abstract: In this work, synthesis of CuInS{sub 2} semiconductor nanoparticles by thermolysis of a mixed solution of CuAc, In(Ac){sub 3} and DDT in coordinating solvent and trioctylphosphine oxide (TOPO) as ligand was developed. CuInS{sub 2} nanoparticles with size of −10 nm and nanorods were obtained and optical properties controlled by adjusting the reaction parameters such as temperature and time. Also the shape of nanoparticles was controlled by various solvents elaborately. The as-prepared nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), UV–vis absorption, and photoluminescence (PL) spectroscopy. With the use of different solvent different morphology obtained. In the presence of oleylamine/octadecene rectangle-like nanorods obtained while with the use of oleic acid sphere-like nanoparticles achieved.
