Abstract
In this work, the ZnS nanowires was synthesized on Au-coated Si substrate by a vapor phase transport (VPT) method. The morphology and structure of the as-synthesized ZnS nanowires were studied through scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). Under excitation of the femtosecond (fs) pulsed laser at 650Â nm, a strong ultraviolet (UV) emission centered at 343Â nm was observed. The peak position and the relationship between the emission intensity and the excitation intensity demonstrated that the UV photoluminescence (PL) be induced by the two-photon absorption (2PA) process. The characteristics and the generation process of the above nonlinear optical phenomena were investigated in detail.
