MOCVD Preparation and Photoluminescence of ZnS Nanowires
View through CrossRef
An original MOCVD reactor was developed to grow zinc sulphide nanowires. The design of a heater system to have an improved control of the process and to obtain homogenous deposition was performed. ZnS nanowires were successfully synthesized by simple metal-organic chemical vapor deposition technique from ZnS powders onto silicon substrates [111]. Substrates were carried out to a process of cleaning and impregnated with gold clusters from a colloidal solution. Field emission scanning electron microscope (FESEM) observations show that the ZnS nanowires have diameters about 10-20 nm and lengths up to several micrometers. Photoluminescence (PL) properties of these synthesized single-crystal ZnS nanowires have been presented. Finally PL detects peaks related to the nanosize effects of the ZnS nanowires.
