Abstract
This article demonstrates the effect of substrate temperature on the pulsed-laser deposition of cadmium sulfide nanoparticles (CdS NPs). Synthesis of CdS NPs on silicon substrates was realized at a temperature range of 150–550 °C. The XRD patterns confirm that CdS NPs showed a wurtzite-hexagonal phase with crystallite size changes between 15 and 24 nm. Also, the SEM images indicate that the temperature is a crucial parameter could determine the morphology of the nanoparticles. Hence, some films exhibited aggregation and cracks causing a significant degradation in the crystalline quality. The results identify that the best quality CdS NPs correspond to an optimal temperature of 450 °C at which the nano-heterostructures could be useful for nanoelectronic applications.
