一、概述: 发光材料是经过加热或磨擦后在黑暗中发出光亮。早在我国远古时代即为人们所知,也就是过去所说的夜光壁现象。后来发光现象作为实验科学研究对象,人们发现在具有荧光性能的材料中,除基质外还有恒量杂质等,而发光性能又与杂质有直接关联。这些杂质即是放射性元素,而放射性元素的发现,使其 First, an overview: Luminescent material is heated or rubbed in the dark after the light. As early as the ancient times in our country is known, that is, the phenomenon of the luminous wall in the past. Later luminescence phenomenon as experimental science research object, it was found in the fluorescent material, in addition to the matrix also has a constant amount of impurities, etc., and luminescence properties and impurities are directly related. These impurities are radioactive elements, which are found by radioactive elements
