Excitation energy dependence of photoluminescence in polycrystalline GaN films by post-nitridation technique

Polycrystalline gallium nitride (GaN) films were prepared on (0001) sapphire substrates by post-nitridation technique. The photoluminescence (PL) spectra of the films show a blue emission (BL) and an ultraviolet emission (UV) at room temperature. We tentatively explain the blue emission in our nomin...
