稀土铝酸锶夜光纤维的光色特性

 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。

Photochromic properties of rare-earth strontium aluminate luminescent fiber

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 luminometer.The experiment results indicated that: the emission peak of yellow and blue luminescent fibers were located at(520 nm),which were caused by transition of Eu~(2+);the crystal phase structure of red luminescent fiber was destructed,making the yellow light emission of 580 nm,this may ...
