Red fluorescent transparent ceramic for laser display and preparation method thereof
The invention discloses red fluorescent transparent ceramic for laser display and a preparation method of the red fluorescent transparent ceramic. The chemical formula of the transparent ceramic is (K0.99-yLiy) 2 (Si1-xMx) F6: 0.02 Mn < 4 + >, M = Ge or Ti, x is the mole percent of M doping, x is greater than or equal to 0.01 and less than or equal to 0.15, y is the mole percent of Li doping, and y is greater than or equal to 0.03 and less than or equal to 0.45; the preparation method comprises the following steps: preparing nanoscale fluoride powder by adopting a hydrothermal synthesis method, and then preparing the fluorescent transparent ceramic by adopting a hot pressed sintering method. Under the excitation of a blue light LD chip with the wavelength of 450 nm, the red light fluorescent ceramic material prepared by the invention realizes the emission of highlight narrow-band red light with the emission wavelength of about 630 nm, has the full width at half maximum of 20-30 nm, the transmittance of 74-78% and the chromaticity coordinate of about (0.682, 0.322), and can be used in the field of laser display.
本发明公开了一种激光显示用红色荧光透明陶瓷及其制备方法。该透明陶瓷的化学式为(K0.99‑yLiy)2(Si1‑xMx)F6:0.02Mn4+，其中，M＝Ge或Ti，x为M掺杂的摩尔百分数，0.01≤x≤0.15，y为Li掺杂的摩尔百分数，0.03≤y≤0.45；先采用水热合成法制备纳米级氟化物粉体，再采用热压烧结法制备得到所述荧光透明陶瓷。本发明制备的红光荧光陶瓷材料的在波长为450nm蓝光LD芯片激发下，实现发射波长630nm左右的高亮窄带红光发射，半高宽为20～30nm，透过率达到74～78％，色坐标为(0.682,0.322)左右，可用于激光显示领域。
