摘要

AlN thin films irradiated with 100 MeV U, 95 MeV Ar and 84 MeV C ions from the HIRFL-SFC (Heavy IonResearch Facility in Lanzhou) were investigated by Infrared spectra and Raman spectra. It appeared A1（TO),A1（LO), E1（To）and E2 Phonon vibration absorption mode to irradiated samples in Fig. 1. 652 cm??1 is vibrationabsorption peak of AlN，with the increase of irradiation dose, the vibration absorption band appear a certainbroadening phenomena. Lighter carbon ion irradiation on the vibration absorption band broadening of the impactis not big. 670 cm??1 is the transverse optical phonon absorption peak of the E1 (TO), after irradiation, the vibrationabsorption peak and the broaden Al-N key into an organic whole. 249 and 660 cm??1 is the E2(low) and E2 (high)
