CdS nanomaterials, furnace angle, vapor phase crystal growth technique
CdS nanomaterials were successfully synthesized at varying furnace angle of 0°, 45°, and 90° with a growth temperature of 8000C and dwell time of 8 hours using the vapor phase crystal growth technique. The synthesized product was a yellow-orange material and was characterized using the SEM, EDX, and photoluminescence spectroscopy. The SEM photomicrographs revealed various nanostructures in a form of nanowires. Energy dispersive X-ray analyses confirmed that CdS nanomaterials showed a uniform composition of Cd and S with a minimal presence of impurities. The PL spectra of the samples revealed intense peaks in the range of 477 nm to 548 nm wavelengths where the energy band gap was obtained at 2.44 eV which is approximately that of CdS
