引言物貭发光的現象很普温,发光物貭的应用也很广泛,如熒光灯、发光分析和結晶燐光体的各种应用。实际上用得最多的发光材料是硫化鋅,硫化鋅-鎘和膩土金属(鈣、鍶、鋇)的硫化物。晶体硫化鋅的发光能力是由于在它的晶格点陣中引入了激活剂粒子(离子或原子)或基貭的中性金属原子而产生的。这一过程是在高溫煅烧ZnS、激活剂和助熔剂混合物的时候发生的。硫化鋅的晶态或者是立方晶系(閃鋅矿型)或者是六角晶系(纤鋅矿型),純硫
INTRODUCTION The phenomenon of light emission is very warm, light-emitting objects are also widely used, such as fluorescent lamps, luminescence analysis and crystallization of various applications ciliary body. In fact, the most frequently used luminescent materials are sulfides of zinc sulfide, zinc sulfide-cadmium and refractory metals (calcium, strontium, barium). The luminescence of crystalline zinc sulphide is due to the introduction of neutral metal atoms in the lattice lattice of activator particles (ions or atoms) or radicals. This process occurs when calcining the ZnS, activator and flux mixture at high temperatures. The crystalline state of zinc sulfide is either cubic (sphalerite) or hexagonal (wurtzite), pure sulfur
