摘　　要：利用分光光度法测定了纳米晶氧化锌对可见光的响应光谱和利用率,并利用量子理论对所得的数据进行分析讨论,结果显示,量子尺寸效应将会导致吸收光谱的蓝移和红移,在光谱波长320nm-1020nm范围内具有60%-100%的光催化效率。The visible spectral response and absorption rate have been determined by spectrophotometer.And the experiment results were analyized and discussed by quantum theory.The results indicate that the main reason for blue-shift and red-shift is quantum size effect.The photocatalytic efficiency of 60%-100% would be obtained in the visible region with the wavelength from 320nm to1020nm.
