Abstract

The optical properties of the nano-ZnO thin films were studied, which were prepared by low temperature wet chemical-method combined with ultrasonic treatment. The thin film could emit the strong UV and blue light. The blue emission was caught by the interstitial zinc (Zn_i), which could be confirmed by Raman spectrum. The relationship of the optical properties and processing parameters was also discussed. The reaction temperature, the reaction time and the different molar ratios of Zn²⁺ to TEA could affect on the intensities of the UV emission and the blue emission of the ZnO thin film, respectively. The mechanism of the phenomena was brought forward by analyzing the FTIR spectrum.
