中文摘要	Visible and infrared photoluminescence was observed from AlN:Er films grown by reactive radio-frequency magnetron sputtering under different powers. X-ray diffraction indicates that the films have a c-axis oriented hexagonal wurtzite structure with an average crystallite size of about 59-83 nm and a strain of about (1.12-1.69) x 10(-3). Green emissions (similar to 540 and 558 nm) from the AlN: Er films are due to the intra-4f(n) transition of Er3+ from H-2(11/2) and S-4(3/2) to I-4(15/2), and infrared (similar to 1535 nm) emissions correspond to I-4(13/2) to I-4(15/2) transitions. Increasing the sputtering power results in larger grain size, lower strain, and enhancement of the luminescence intensity. (c) 2006 American Institute of Physics.
