The photoluminescence of ZnO films deposited on Si substrates by reactive dc sputtering has been studied by using a synchrotron radiation (SR) light source. The excitation spectra show a strong excitation band around 195nm related to the 390nm emission band. Under SR vacuum ultraviolet excitation, a new emission band peaked at 290nm was found for the first time, besides the ultraviolet emission band (390nm) and green band (520nm).
