讨论了影响长余辉发光粉特性的主要因素。介绍了测试其发光特性的基本要求。在此基础上描述了一种测试长余辉荧光粉的新装置。它使用模拟D65光源作为激发光源,使用一台自动量程光度计来测量长余辉荧光粉亮度。从激发源到样品的激发光,以及从样品到光度计的发射光均由光纤进行传导。激发光通过耦合在二光纤中间的电动快门实施控制。装置的工作由计算机控制。需要特别指出的是装置可以在正常照明条件下工作。实测表明装置的设计非常巧妙和实用。

The main factors influencing the emitting characteristics of longtime afterglowing pigments are briefly discussed. The essential requirements for measuring the emitting characters are introduced. A new apparatus satisfied for the measurement of longtime afterlowing pigments is developed. It uses D 65 simulator as the stimulating source and uses auto-range photometer to measure luminance of longtime afterglowing pigments. The light from stimulating source to the pigment sample and the emitting light from the pigment sample to the photometer are transmitted by optical fibres. The stimulating light is controlled by an electric shutter which is coupled between the two optical fibres. The apparatus operated by a computer. It would be specially mentioned that the apparatus can be operated under the normal lighting condition. The measurements shows design of the apparatus is very ingenious and practical.
