利用阳极氧化法制备的氧化铝薄膜是非晶态的并且表面呈高度有序的多孔结构.经过太阳光照射后氧化铝薄膜具有明显的热释光现象,发光峰值出现在190℃,表明其对太阳光敏感.经过电子束辐照后薄膜的热释光特性与制备时电解液浓度和退火处理的时间有关,其中制备过程中电解液浓度为0.4mol/L热释光现象最明显,退火时间为5小时的热释光现象最明显.

Alumina oxide films prepared by anodic oxidation method are amorphous and have highly or-dered pore structures. The alumina oxide films irradiated with sunlight have obvious thermoluminescence (TL)phenomenon, the glow peak occurs at 190℃, and this shows that the films are sensitive to sun-light. The TL relative intensity of the films after electron-besm irradiation is related to electrolyte con-centration and annealing time. When electrolyte concentration is 0. 4mol/L, the films present stronger TL intensity. When annealing time is 5 hours, the films present more obvious TL phenomenon.
