  1. We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band

    另外,我們還對薄膜致發性質進行了分析和研究,結果表明:納米結構zno薄膜的紫外發來源於子的復合發, pl譜的邊發峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小,使薄膜的有效隙增; zno薄膜的紅色發,一方面是zno顆粒尺寸的減少,間的子發峰越來越弱直至猝滅,另一方面主要是與zno晶格中的o空位有關,由深能級復合發引起紅
