The nano-structured ZnO thin film has been grown by molecular beam epitaxy on an Si (100) substrate. The emission spectra of ZnO samples were measured with the photon counting method in the temperature range from 18 to 140K by using the synchrotron radiation up to the vacuum ultraviolet region. Under the excitation of 196nm, two main emission bands have been observed, which peak at 330 and 430nm approximately...
