Abstract

Abstract: A unique ZnO nanostructures were synthesized with hydrothermal method. The composition, morphology and size of the sample was determined with XRD, EDX and FE-SEM. Photoluminescence(PL) properties were studied by room-temperature PL spectra, temperature-dependent shifts and its Gaussian-fitted spectra. The results of XRD, EDX and FE-SEM analysis show that the products are the hexagonal wurtzite ZnO nanostructures, with a length of ~10 μm and diameter of ~2 μm; UV, violet and green peaks, which exhibit blue-, S-shaped (red-blue-red) and redshift, respectively, and the decrease of intensity, with the temperature increasing from 8 K to 300 K, are observed in the PL spectra. The original and different temperature dependence of the UV, violet and green peaks is discussed.

Key words: Hydrothermal method, ZnO, Nanostructure, Temperature-dependence PL spectrum
