Abstract:
A high color rendering index (CRI) white light emitting device from a short wavelength semiconductor die is encapsulated with nanoparticle-loaded resin. Trichromatic wavelength conversion micro-particles are dispersed layer by layer in a converting sequence from a long emission spectrum to a short emission spectrum. The refractive index of wavelength conversion micro-particles matches that of the nanoparticle-loaded encapsulants.
