Abstract
The single phase CGS nanoparticles were synthesized by solvothermal method. The optimal annealing regime of synthesis stage was determined as 180 °C for 12 h followed by an extra annealing at 230 °C for 12 h. The phase improvements were studied using X-ray diffraction (XRD) patterns. Grain size ranging from 20–50 nm was obtained by SEM and TEM images and confirmed by Scherrer's formula. Band gap of 2.48 eV and a broad PL spectrum peaking at 3.16 eV were resulted respectively from studies on UV-Visible absorption and photoluminescence (PL) patterns of the synthesized nanoparticles.
