论文部分内容阅读
Polycrystalline gallium nitride films with hexagonal structure were prepared by a post-nitridation technique. A strong blue photoluminescence located at 458 nm and a UV photoluminescence located at 368 nm were observed at room temperature. The 368nm peak is PL from band-edge emission. The blue luminescence is attributed to the transition from deep donor level to the valence band.
