  9. 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
