LED(light-emittingdiode，发光二极管)照明的提倡不仅有利于社会和环境的可持续性发展，还可以带动相关产业，提升我国照明产业的竞争力。而开发具有良好发光特性的荧光粉是得到高亮度、高发光效率、高显色性白光LED的关键所在。目前国内外都在研究优化固相法生产工艺或开发新制备工艺，以解决荧光粉存在的主要问题——亮度和显色指数偏低。 本文对高温固相法制备稀土掺杂YAG（yttriumaluminumgarnet，Y3Al5O12，钇铝石榴石）荧光粉这种方法进行了深入研究：通过对YAG荧光粉的温度、时间、掺杂离子种类、掺杂方式等制备工艺的优化，确定了稀土掺杂荧光粉的制备条件；通过XRD...Green lighting style was put forward at the background of global warming and energy saving. White LED (light-emitting diode) is recognized as the green lighting product and will substitute the traditional bulbs. In present, the way employing an InGaN/GaN LED chip coated by YAG（yttrium aluminum garnet，Y3Al5O12）yellow phosphors is the main way to get w-LED. As a result, YAG yellow phosphor becomes c...学位：工学硕士院系专业：化学化工学院材料科学与工程系_材料物理与化学学号：1932005130194
