Dy3+ and Eu3+ ions with different doses were implanted into AlN thin films grown by hydride vapor phase epitaxy method. For Dy doped AlN, results of X ray diffraction and Raman scattering show that the compressive stress of the sample increases with the increase of Dy3+ dose. When the Dy3+ dose increases from 5 x 10(14) at/cm(2) to 1 x 10(15) at/cm(2), the compressive stress of samples is close to saturation. For Dy3+ and Eu3+ co-doped AlN, according to the cathodoluminescence spectra, a possible energy transfer process between Dy3+ and Eu3+ is proposed. In addition, through changing the dose ratio of Dy3+ respect to Eu3+ ions, the chromaticity coordinates and color temperatures of Dy3+ and Eu3+ co-doped AlN can be effectively regulated.
