1基于蓝光LED的白光器件:用于固体发光的小颗粒YAG:Ce型荧光粉的合成显示文摘文章介绍了小颗粒YAG:Ce荧光粉的三种合成方法。这种荧光粉受到蓝光LED发出的光线的激发会发出黄光。在合成的pcLEDs里,蓝光和黄光混合形成了白光。本文解释了这种涂有YAG:Ce荧光粉的pcLED的色点的依赖性以及通过添加修复晶格点阵的催化剂以改变这种依赖型的方法。另外,文章还讨论了Ce件聚集中心的YAG:Ce荧光粉的效率的测量、烧成温度、激发波长。Jack Silver Robert Withnall George Fern Anthony Lipman 2008电子器件2008,31,1:4

6蓝光LEDs的转换荧光粉发光效率的测量显示文摘本文研究了YAG:Ce荧光粉的色氟红移的现象。当YAG晶格点阵中的Y被Gd激发或添加了Pr作为Ce的共同催化剂时就会发生这种现象。测量了在(Y,Gd)AG:Ce和YAG:Ce,Pr荧光粉样品内部的效率,其激发光线的波长为470nm。其结果表明这两种荧光粉的发光效率分别随着Gd和Pr聚集而降低。SrGa2S4:Eu。是另外一种常用的转换蓝光LED的颜色的荧光粉。室温下,这种荧光粉效率很高,理论上其发光效率比YAG:Ce的发光效率高出33%。对这种荧光粉效率的测量结果表明其制作过程是影响性能的主要因素。将这种荧光粉印刷在放在一个或多个蓝光LED前面的屏幕的表面,测得其发光效率高达364lm/W。Jack Silver Robert Withnall Anthony Lipman 2008电子器件2008,31,1:1
