N2 - Synthesis and characterization of CuInS2 quantum dots (QDs) and CuInS2 QDs/TiO2 with varied reaction temperature (200; 215°C) and TiO2 precursor concentrations was conducted using wet-chemical method. At higher temperature, CIS exhibited deep-red emissions and enhanced the photoluminescence (PL) intensity, indicating the reduction of surface defects. With the addition of TiO2 precursor, particle sizes decreased, bandgap energy increased, and the absorption edge shifted to the blue region. The UV-Vis absorption shifting expands the light-absorbing region. CIS hybridized with 150 µl TiO2 precursor (CIS-TO 150) has particle sizes 2.15 nm with tetragonal chalcopyrite crystal structure and bandgap energy 2.72 eV. This property gives a great potential for wide range of application via photocatalytic mechanism under visible light.
