Abstract
A light emitting device comprises a light emitting diode (LED) chip having a dominant wavelength in a range from about 390 nm to about 560 nm, an encapsulant in optical communication with the LED chip, and coated phosphor particles dispersed in the encapsulant. Each of the coated phosphor particles comprises (a) a luminescent particle having a first refractive index at the dominant wavelength, and (b) an optical coating on the luminescent particle, where the optical coating has a second refractive index at the dominant wavelength. The second refractive index is between the first refractive index and a refractive index of the encapsulant at the dominant wavelength.
