Notes:
ZnO nanorods were prepared by a hydrothermal reaction in the presence or absence of PVP(polyvinyl pyrrolidone). The obtained products were characterized by means of X-ray diffraction,scanning electron microscopy, transmission electron microscopy, Fourier transform infrared, UV-Visabsorption (UV) spectroscopy and photoluminescence (PL) spectroscopy. The results suggest that PVPplays an important role in the preparation of ZnO nanorods. The UV absorption spectrum showed PVPincreases the UV-shielding ability but doesn’t influence the transparency in the visible light region. Aweak UV emission at 353 nm of PL spectra exhibit the surface of ZnO nanorods is passivated andoxygen-related defects is supplied by PVP
