METHODS OF FORMING WARM WHITE LIGHT EMITTING DEVICES HAVING HIGH COLOR RENDERING INDEX VALUES AND RELATED LIGHT EMITTING DEVICES

摘要

Methods of forming a light emitting device are provided in which a solid state lighting source is heated and a luminescent solution is applied to the heated solid state lighting source to form the light emitting device. The luminescent solution includes a first material that down-converts the radiation emitted by the solid state lighting source to radiation that has a peak wavelength in the green color range and that has a full width half maximum emission bandwidth that extends into the cyan color range, and at least one additional material that down-converts the radiation emitted by the solid state lighting source to radiation having a peak wavelength in another color range.
