    摘要:

    使用真空電子束交替蒸發(fā)的方法，在DMD-450型真空鍍膜系統(tǒng)中，通過(guò)調(diào)整Sr2CO3、Al2O3、Eu2O3、Dy2O3獨(dú)立原料靶材的蒸發(fā)時(shí)間和蒸發(fā)周期次數(shù)，制得藍(lán)綠色(GF) 和藍(lán)紫色(PF)發(fā)光膜。在以鋁酸鹽為基質(zhì)的蓄能發(fā)光膜中，改變鋁與鍶的摩爾比，將出現(xiàn)Eu2+的4f65d1→4f7多顏色寬帶躍遷和Eu3+的5D0→7FJ窄帶躍遷。還原熱處理?xiàng)l件對(duì)發(fā)光膜的發(fā)光性能有著重要影響：溫度明顯影響結(jié)晶狀態(tài)；還原氣氛中H2量對(duì)發(fā)光膜的發(fā)光顏色影響較小，但會(huì)影響其相對(duì)發(fā)光強(qiáng)度。

    Abstract:

    In the DMD-450 vacuum deposition system, the evaporation time and cycle times for Sr2CO3, Al2O3, Eu2O3, and Dy2O3 targets were changed by Alternate Electron Beam Evaporation method to prepare the blue-green film(GF) and the blue-purple film(PF). Variation of Al2O3/SrO molar ratio in the light-storing ceramic films with aluminate base will produce many different crystal phases which induce the various broadband 4f65d1→4f7 transitions of Eu2+ and the narrowband 5D0→7FJ transitions of Eu3+. Annealing conditions has great influence on the luminescent properties of the films, among which annealing temperature affects crystallization and the H2 proportion in annealing atmosphere has little influence on the film color but will affect its intensity.
