摘　　要：利用磁控溅射制备稀土掺杂铝酸锶薄膜前驱体,再将前驱体置于800℃、900℃、1000℃和1100℃弱还原气氛热处理,得到铝酸锶长余辉发光薄膜。薄膜的物相结构随热处理温度升高而发生改变,逐渐由SrAl_2O_4相转变为Sr_4Al_(14)O_(25)相,光致发光性能随之发生改变。Rare earth ions doped long persistent film precursor was fabricated by radio frequency magnetron sputtering. The precursor was annealing the films in weak reducing atmosphere under 800℃ 900℃, 1000 ℃ and 1100 ℃, respectively. Then, the long persistent films were obtained. The structure of the films varied by the annealing temperature, and the photolumineseence of films were studied.
