我们知道,物体的发光是物体内部以某种方式吸收外界作用的能量,转化为光辐射的过程。根据外界激发方式不同,可以区别为光致发光、电致发光、阴极射线发光、放射线发光等等。就发光物质而言,又包括了无机物和有机物两大类。 We know that the glow of an object is the process by which the energy of the outside world is absorbed by the interior in some way and transformed into light radiation. According to the different external excitation mode, you can distinguish between photoluminescence, electroluminescence, cathode ray emission, radioactive light emission and so on. In terms of luminescent materials, but also includes two categories of inorganic and organic matter.
