一般卤素化合物晶体在可见光区域是透明的 ,经过合适的化学或物理方法处理 ,可在晶体中形成色心而具有特有的颜色。常用的物理方法是短波长紫外线辐照或射线辐照 (X射线 ,γ射线或电子束射线 )。通常经这些辐照方法处理后 ,可使卤素化合物晶体样品均匀着色。自上世纪 90年代以
General halogen crystal compounds in the visible light region is transparent, after the appropriate chemical or physical treatment, can form a color center in the crystal and has a unique color. Common physical methods are short-wavelength UV radiation or radiation (X-rays, gamma rays or electron beam radiation). Normally after these irradiation methods, the halogen compound crystal samples can be uniformly colored. Since the 90s of last century
