Inorganic red perovskite quantum dot integrated blue chip: a promising candidate for high color rendering in w LEDs
Inorganic perovskite quantum dots (IPQD) assisted by a yellow emitting YAG:Ce phosphor were integrated on a blue LED chip. The red perovskite quantum dot (R PQD) assisted YAG:Ce phosphors exhibit warm white light with CCT (3328 K) high color rendering index (CRI 84.7) and a super high value of saturated red color component R9 as 96. The results demonstrate that the inorganic red perovskite quantum dot assisted yellow phosphor material may be a potential candidate for the generation of warm white light for indoor lighting applications.
