Filling the cyan gap is key element in achieving full-spectrum illumination using violet chip to excite red, green and blue phosphors. However, designing phosphors suitable for light excitation with excellent performance remains challenging. Herein, a novel phosphor Ba9Lu2-x-nSi6O24:xCe (n-BLS:Ce) multiple crystal sites of Ba2+ Lu3+ Ce3+ ions was designed prepared via crystal-site engineering. The at emit ultraviolet 385 nm under 325 excitation, 485 395 excitation. favorable occupation could be realized by introducing Lu vacancies. Significantly, emission intensity Ba9Lu1.4Si6O24:0.3Ce (n0.3-BLS:Ce) vacancies effectively improved 47% compared Ba9Lu1.7Si6O24:0.3Ce (n0-BLS:Ce) without And 150 °C retains 96% that room temperature. color rendering index increases from 87.9 94.5 after supplementing w-LEDs devices combining commercial green, chip, indicating its potential practical application lighting. This work also provides new ideas design development efficient high-quality light-emitting materials.
