We report on room temperature photoluminescence on GaN films grown by metal organic chemical vapor deposition (MOCVD). A NdYAG pulsed-laser at 266nm illuminates the films. Two components, at 363nm and 370nm, are identified in the near band edge structure on the spectra. A laser threshold of 700±150kWcm−2 is evidenced and corresponds to random lasing in the GaN film. A drastic narrowing of the spectral...
