CaAl₁₂O₁₉:Mn red-emitting phosphor has been synthesized by a novel sol-gel route for the possible applications for white LEDs or white OLEDs. The sol-gel derived CaAl₁₂O₁₉:Mn phosphor was crystallized into a single crystalline phase and showed red luminescence excited by NUV and blue wavelength. The main red emission peak was at 653 nm with satellite peaks while the excitation bands consisted of three peaks around 334 nm, 397 nm, and 468 nm. The sol-gel derived CaAl₁₂O₁₉:Mn red-emitting phosphor would be compatible for the possible application of white LEDs or white OLEDs through NUV- or blue- excitation.

溶胶凝胶法合成CaAl12Ø19：Mn荧光粉和近紫外/蓝色激发的红色发光

已经通过新颖的溶胶-凝胶路线合成了CaAl ₁₂ O ₁₉：Mn红色发光磷光体，以用于白色LED或白色OLED的可能应用。溶胶-凝胶衍生的CaAl ₁₂ O ₁₉：Mn磷光体结晶为单晶相，并显示出由NUV激发的红色发光和蓝色波长。主要的红色发射峰在653 nm处有卫星峰，而激发带由334 nm，397 nm和468 nm附近的三个峰组成。溶胶-凝胶衍生的CaAl ₁₂ O ₁₉：Mn发射红色荧光粉将通过NUV或蓝色激发与白光LED或白光OLED的可能应用兼容。
