摘要 针对传统光电成像传感器对紫外响应的敏感度不高,通过研究有机金属配价物的发光机理与光致发光特性,用真空蒸镀的方法制备出有机金属配价物三(8-羟基喹啉)铝(Alq3)薄膜。用紫外光激发Alq3薄膜发现有较强的黄绿光产生,中心波长位于510nm左右,并且激发光谱较宽(250nm~425nm)。该薄膜在可见光波段有很好的透过性,这使得可见光可以透射薄膜,基本无损失地到达传感器光敏感窗,从而增强了光电成像传感器的紫外响应。 Traditional Optoelectric imaging sensors have lower response in ultraviolet region particularly.This paper has investigated the luminescence mechanism and photoluminescence properties of organometallic compound tris-(8-hydroxyquinoline) aluminum thin films,which are deposited on quartz substrates by means of vacuum evaporation.It is showed that these coatings are emitted a green glow centered at ~ 510 nm,together with a wide excitation spectrum field from 250 nm to 425 nm.The films have such a nice permeability in visual field that ‘the ultraviolet radiation’ transmits the film to the silicon window of sensor with little loss,enhancing the ultraviolet responsibility of image sensors.
