Full-spectrum high-color-rendering-index fluorescent ceramic for solid-state illumination and preparation method thereof
The invention discloses full-spectrum high-color-rendering-index fluorescent ceramic for solid-state illumination and a preparation method of the full-spectrum high-color-rendering-index fluorescent ceramic. The general chemical formula of the fluorescent ceramic is (Ca1-x-zCexPrz) 3 (Sc1-yMny) 2Si3O12, in which x is the molar percentage of Ca < 2 + > substituted by Ce < 3 + >, and x is more than or equal to 0.001 and less than or equal to 0.005; y is the mole percent of Sc < 3 + > substituted by Mn < 2 + >, and y is more than or equal to 0.001 and less than or equal to Z is the molar percentage of Pr < 3 + > replacing Ca < 2 + >, and z is more than or equal to 0.0001 and less than or equal to 0.005 According to the fluorescent ceramic prepared by the invention, the luminescent wavelength of the material can be adjusted by properly doping Pr < 3 + > and Mn < 2 + >, so that the material has a wider application range. Under the excitation of a blue light LED chip with the wavelength of 450 nm, the fluorescent powder can emit fluorescence with the wavelength covering the range of 525-750 nm, and the color rendering index is 85-92. When the environment temperature is 150 DEG C, the luminous intensity of the fluorescent ceramic is kept at 75%-90%.
本发明公开了一种固态照明用全光谱高显指荧光陶瓷及其制备方法。该荧光陶瓷的化学通式为：(Ca1‑x‑zCexPrz)3(Sc1‑yMny)2Si3O12，其中x为Ce3+取代Ca2+位的摩尔百分比，0.001≤x≤0.005；y为Mn2+取代Sc3+位的摩尔百分比，0.001≤y≤0.01；z为Pr3+取代Ca2+位的摩尔百分比，0.0001≤z≤0.005。本发明制备的荧光陶瓷通过适当的掺杂Pr3+和Mn2+，可以调节材料的发光波长，使得材料具有更广泛的应用范围。在波长为450nm蓝光LED芯片激发下，能够发射波长覆盖525～750nm范围的荧光，其显色指数为85～92。当环境温度为150℃时，所述荧光陶瓷的发光强度保持在75％～90％。
