Abstract
Zinc Selenide nanoparticles were synthesized via solvothermal method using zinc chloride and selenium powder. X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Ultraviolet – Visible spectroscopy and Photoluminescence Spectroscopy were used to analyze the sample. XRD confirmed the cubic zinc blende phase and the mean size of the particle was determined using Scherrer formula was 65nm. SEM image revealed the spherical shape of the particles. Photoluminescence spectra with excitation wavelength (325nm) show a weak emission peak at 555nm.
