Fluorescent ceramic with high color rendering index and high thermal conductivity, preparation method and application in laser display
The invention belongs to the technical field of inorganic luminescent materials, and discloses fluorescent ceramic with high color rendering index and high thermal conductivity, a preparation method and application in laser display or high-color-rendering-index laser lighting equipment. The fluorescent ceramic with high color rendering index and high thermal conductivity is composed of an Al2O3 ceramic substrate, garnet-based fluorescent powder or cyan light, green light, yellow light, red light fluorescent powder and a fluxing agent, wherein the garnet-based fluorescent powder or cyan light,green light, yellow light and red light fluorescent powder and the fluxing agent are distributed in the Al2O3 ceramic substrate. The preparation method of the high-color-rendering-index and high-thermal-conductivity fluorescent ceramic comprises spark plasma sintering (SPS) or vacuum high-temperature sintering or hot isostatic pressing sintering. The thermal conductivity of the high-color-rendering-index high-thermal-conductivity fluorescent ceramic is 10-30 W*m < 1 > K < 1 >, an excitation source is blue light generated by a blue light laser diode or ultraviolet light generated by an ultraviolet light laser diode, an emission peak is broadband emission, the emission wavelength is adjustable (480-750 nm), and the color rendering index is 75-95.
