摘要: 使用XRD、荧光光谱仪、光谱扫描色度计及照度计对日光下呈现红、黄、蓝三基色的稀土铝酸锶夜光纤维的物相、发光光谱、色度及余辉性能进行了表征,并作简要分析。结果表明:黄、蓝色夜光纤维发射峰处于520 nm处,为Eu2+跃迁;红色夜光纤维晶格遭到破坏,产生580 nm黄光发射,这可能是铝酸锶中Dy3+发生跃迁;3种纤维所呈现的色光依次为黄、黄绿、绿光;3种夜光纤维的发光照度呈现红色<蓝色<黄色<稀土铝酸锶的规律,相对于稀土铝酸锶,夜光纤维的余辉寿命获得一定延长。

Abstract: The phase, luminescence spectrum, chromaticity and afterglow properties of red, yellow and blue rare-earth strontium aluminate luminescent fibers were measured by XRD, fluorescence spectrometer, spectral scanning-meter and illumi- nometer. The experiment results indicated that: the emission peak of yellow and blue luminescent fibers were located at 520nm,which were caused by transition of Eu2+; the crystal phase structure of red luminescent fiber was destructed, making the yellow light emission of 580nm, this maybe the transition of Dy3+of rare-earth strontium aluminate; the chromatic light of these three fibers were yellow, yellow-green and green; the illumination of these luminescent fibers showed the rule of red
