Optical waveguiding LiNbO3 film was grown on (001)-oriented crystalline SiO2 substrate by pulsed laser deposition. The film is highly (012) textured and has smooth surface. Its photoluminescence (PL) spectra were obtained by using the 514.4 nm line excitation of Ar+ laser, displaying a broad band peaked at 2.2 eV at room temperature and three well-resolved luminescent bands peaked at 2.3, 2.2, and 2.14 eV at liquid nitrogen temperature with different polarization properties. Spectral analysis indicates that these obtained PL bands arise from the self-trapped excitons and the E′ defect pairs connected with oxygen vacancies in the LiNbO3 film. © 1996 American Institute of Physics.
