Abstract
Narrow-band line-emitter phosphors offer improved lm/W for white LEDs, while maintaining high CRI. Especially Eu3+-doped phosphors are ideal from an emitter perspective. However, using Eu3+ for practical LEDs is hampered by the lack of absorption in the blue spectral region. To solve this problem, we have developed nano-engineered phosphors harvesting interparticle energy transfer (IFRET), an innovative approach to sensitize Eu3+, and other ions, in the blue spectral range. In this presentation, we will share our progress on our IFRET materials, as well as demonstrate high-quality (high QY and small-size) nano-YAG phosphors.
