Effects of growth ambience, annealing ambience and temperature on the photoluminescence (PL) emission properties of ZnO films deposited on Si (100) substrates by RF magnetron sputtering have been investigated. After annealing, the crystal quality of ZnO films was markedly improved, and the intensity of UV emission peak increased obviously. By varying the flow rate ratio of 02/Ar, annealing atmosphere in oxygen-deficient or oxygen-rich ambience and heating temperature during deposition, the evolution of peak intensities and positions for blue and green emission is formed. This is attributed to the deposition and annealing parameters that control the desorptions and adsorptions of oxygen atoms on the films, and leads to the changes of concentrations of Zinc and oxygen vacancies in the films.
