System and method for forming a thin-film phosphor layer for phosphor-converted light emitting devices
A thin-film phosphor layer can be formed by an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly-deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film.

White light source system
A light emitting device including a substrate, a first light emitter to emit light having a first color temperature, and a second light emitter to emit light having a second color temperature, in which the first light emitter has a first converter including first phosphors and a first resin, each first phosphor having different halfvalue widths, the second light emitter has a second converter including second phosphors and a second resin, each second phosphor having different peak wavelengths, at least one phosphor of the first converter has a half-value width of 33 nm to 110 nm, a distance between peak wavelengths of at least two phosphors of the second converter is 150 nm or less, and at least one phosphor of the first converter has a particle size of 5 um to 50 um.
