本文介绍一种用紫外线作激励源的无机发光材料,适用于荧光灯。本材料被紫外线激励时,能发出可见光、绿光或绿/黄光,还能发出适用于复印机之类机器上比激励光波长的紫外线。 该材料的缺点是亮度低,又因含有铕、铽等元素,价格昂贵。 本发明提供的是一种亮度高、价廉的无机发光材料。 实施例1 碳酸钙:55g 硫酸铵:100g 六硝酸铈二铵:21g
This article describes a kind of inorganic luminescent material with UV excitation source, suitable for fluorescent lamps. The material is excited by ultraviolet light, can emit visible light, green light or green / yellow light, but also issued for machines such as copiers than the excitation wavelength of ultraviolet light. The disadvantage of this material is low brightness, but also because of containing europium, terbium and other elements, expensive. The invention provides an inorganic luminescent material with high brightness and low cost. Example 1 Calcium carbonate: 55 g Ammonium sulfate: 100 g Diammonium hexonitrate: 21 g
