The purpose of this study was to develop new garnet phosphors for white LED applications. Numerous compositions were designed to explore new garnet structure phosphors. Among the candidates, Y2LuCaGaAl2SiO12 was selected as a host material, and Y2−xLuCaGaAl2SiO12:xLn (0 ≤ x ≤ 0.12; Ln = Ce3+, Eu3+, and Tb3+) phosphors were prepared by using the solid-state reaction method. The Rietveld refinement results showed that Y2−xLuCaGaAl2SiO12:xLn phosphors had a garnet type cubic structure with the Ia![[3 with combining macron]](https://www.rsc.org/images/entities/char_0033_0304.gif)
d space group. The prepared phosphors emitted efficient green, red, and green light by doping Ce3+, Eu3+, and Tb3+, respectively, in Y2LuCaGaAl2SiO12, and showed good luminescence efficiency and high emission color purity. These results demonstrate that the Y2−xLuCaGaAl2SiO12:xLn phosphors can be useful for white light-emitting diode (LED) and solid-state lighting system applications.

适用于白色LED的 新型Y 2 LuCaAl 2 SiO 12：Ln（Ln = Ce 3+，Eu 3+和Tb 3+）荧光粉†
这项研究的目的是开发用于白色LED应用的新型石榴石荧光粉。设计了许多成分以探索新的石榴石结构磷光体。间的候选，Y 2 LuCaGaAl 2的SiO 12被选作主体材料，和Y 2- X LuCaGaAl 2的SiO 12：X LN（0≤ X≤ 0.12; Ln为铈3+，Eu的3+和Tb 3+通过使用固态反应方法制备磷光体。Rietveld精炼结果表明，Y 2− x LuCaGaAl 2 SiO 12：xLn磷光体具有Iad空间群的石榴石型立方结构。制备的荧光粉通过分别在Y 2 LuCaGaAl 2 SiO 12中掺杂Ce 3+，Eu 3+和Tb 3+发出有效的绿，红和绿光，并显示出良好的发光效率和高发射色纯度。这些结果表明，Y 2- x LuCaGaAl 2 SiO 12：x Ln磷光体可用于白色发光二极管（LED）和固态照明系统应用。
