| Abstract(in English) | Optical properties of ZnO thin films, which were grown through a reaction between dimethylzinc and high-energy H_2O produced by a Pt-catalyzed H_2-O_2 reaction, were measured. The films were grown directly on a-plane (11-20) sapphire substrates at 773-873 K without a buffer layer. The optical transparency of the ZnO films in the visible and near-infrared regions was more than 95% of that of a substrate without ZnO film. Intense band-edge luminescence was observed at 3.29 eV at room temperature, and its FWHM value was 104 meV. The most intense PL peak at low temperature (5 K) was observed at 3.3803 eV, and was assigned to luminescence from donor bound excitons, the associated FWHM value being 1.0 meV. At the same time, free exciton peaks derived from FX_A (n=1) and FX_A (n=2) were observed. |
