| Abstract: | CdS nanowires were successfully synthesized via a solvothermal route with the assistance of poly(vinyl alcohol) (PVA). The prepared sample was characterized by XRD, TEM, HRTEM, UV-Vis, and PL(photoluminescence) emission spectrum. The results indicated that the wurtzite CdS nanowires, with typical diameter of 70 nmand length up to 10 μm, had a preferential growth direction of 001] and showed a quantumconfinement effect. Based on the results of comparative experiments, a PVA-assisted growth mechanismwas proposed. |
