Abstract:
An inorganic composite luminescent material includes inorganic illuminants. An inorganic illuminant includes an inorganic luminescent particle configured to emit light, and a porous coating surrounding the inorganic luminescent particle. The porous coating has a plurality of pores. The inorganic composite luminescent material can further include scattering agents within at least a portion of the plurality of pores in the porous coating of the inorganic illuminants. The scattering agents are configured to scatter the light emitted from the inorganic luminescent particles.
