Y3Al5O12 (YAG) doped with Ce3+ ions is widely used as a phosphor for the generation of white light in LEDs. However, the material presents intrinsic drawbacks: (1) a yellow emission band lacking a red component, leading to a “cold” white light and (2) limited cerium incorporation (~ 3mol%), resulting in poor absorption and thus limiting the external quantum efficiency (EQE) of the LED device. In order...
