彩色发光涂料的光学测量

Optical measurement of coloured luminous coatings

彩色发光涂料是一种高光效、长余辉的光致发光材料。当对其进行光学测量时，为避免因激发光被探测器接收而对测量结果产生的影响，提出在实验中如何设定特殊的装置，从而保障对发光涂料的光学特性进行有效的测量。根据光度学理论中有关照度和发光亮度的关系，通过实验对三种不同的彩色发光涂料在同样光照条件下的亮度测量，同一种发光涂料在不同颜色光照下的发光亮度比较，以及在彩色发光涂料的亮度衰减情况给出了测量的结果。

That coloured luminous coating is a kind of material of photoluminescence with higher luminescence efficiency and longer luminescence persistence is showed. When measuring the optical properties of such material it should be considered that the exciting light can affect the result of measurement if it exposes directly to the detector. It is introduced to use a special experimental provision for effectively measuring the optical properties of coloured luminous coating that will avoid to detect the exciting light. Based on the theory of photometry about the relationship between illuminance and luminance, some measuring results of luminances are given by experiment. That includes the luminances of three different coloured luminous coatings excited by the same light, the luminance of a coloured luminous coating excited by different coloured lights and attenuation of luminance of a coloured luminous coating.
