Green light conversion material with high luminous efficiency and preparation method thereof
A green light conversion material with high luminous efficiency has a chemical general formula of yLu3Al5O12-(1-y) (CexLu1-x) 3Al5O12, x is the atomic percentage of Ce < 3 + > doped Lu < 3 + > site, y is the mass ratio of LuAG replacing Ce: LuAG, 0 lt, 0 < = y < = 0, 0 < = y < = 0, 0 < = y < = 0, and 0 < = y < = 0. X is less than or equal to 0.01, 0lt; yt; Yt; 1. The preparation method comprises the following steps: respectively weighing Lu2O3 powder, Al2O3 powder and CeO2 powder as ceramic powder according to the stoichiometric ratio in the chemical general formula; the preparation method comprises the following steps: by taking a solvent as a ball-milling medium, putting ceramic powder and a sintering aid into a ball-milling tank for ball-milling, and then sequentially carrying out drying, sieving, cooling and other forming and calcining to obtain a ceramic biscuit; and the ceramic biscuit is subjected to sintering, annealing and double-sided polishing in sequence, and the green light conversion material with the high luminous efficiency is obtained. The preparation method is simple, and the prepared conversion material can improve the light conversion efficiency and the transmittance in a visible light region, so that high-lumen-density green light is obtained.
