The effects of process parameters, such as mixing temperature, concentration of the solutions and their ratios, on the particle morphology and sizes were investigated. The sizes of the prepared ZnO were estimated by x-ray diffraction (XRD), Brunauer-Emmet-Teller(BET) technique and laser scattering method. Particles with a size ranging from 20 to 50nm were obtained with solution concentrations: [ZnCl2]=0.1M and [KOH]=0.2M. Some metastable complex phases of ZnO were observed by XRD as the precipitated powder was heated up to 100℃. The synthesized ZnO showed photoluminescence excitation with a peak at 325nm and emission at 400nm. Pang Lin 林鵬 2003 學位論文 ; thesis 83 zh-TW
