Abstract High quality AlN thin films doped with TbF3 were prepared by rf magnetron reaction sputtering. High purity AI metal and TbF3 were used as target materials with N2 and Ar as sputtering gases. The influence of preparation conditions on the photoluminescence brightness was studied, and the electroluminescence was found to have a similar dependence on the concentration of TbF3 and substrate temperature. The characteristic emission of Tb3+ ions was obtained in an AIN:TbF3 alternating current thin film electroluminescence device prepared with 600°C substrate temperature and 4.0mol% concentration of TbF3.
