摘要：

Highly crystallized BaWO4 films (45 x 30 mm(2)) have been prepared by cell electrochemical technique at room temperature. X-ray diffraction measurement reveals that the as-prepared BaWO4 thin films have a scheelite structure. Under cell conditions, due to the decrease of crystal size and disappearance of large clusters, films' homogeneity has been improved markedly. With the UV excitation the peculiar and tunable luminescence of BaWO4 films has been observed. Investigations uncover that exciting energies can be transferred among different emission centers, and that the yellow emission is probably relevant to the vacancies of Ba in the outermost layers of films.
