摘要：
Mg0.5Zn0.5O films were prepared on quartz glass substrates by sot-gel method. Structure and optical properties of Mg0.5Zn0.5O film were studied. Results indicated that Mg0.5Zn0.5O film deposited on quartz glass is composed of two structures of ZnO hexagonal and MgO cubic. SEM image revealed that the film was homogenous and the average grain size of crystal was 40nm. Absorption spectrum indicated the absorption edge of hexagonal and cubic structures located in 332nm and 271m respectively. The absorption edge of cubic structure locates in the solar blind region. The luminescence spectrum of sample is composed of three peaks at 383.7nm(3.23eV), 442.9nm(2.80eV) and 533.9nm(2.32eV) respectively. The peak of excitation spectrum is at 379nm(3.28eV).
