    摘要: A light emitting device in which a primary light generator, such as a light emitting diode (LED) or laser diode, is operable to emit a primary light that is received by a body of wavelength converting material. A portion of the primary light is absorbed by the body of wavelength converting material and is emitted as secondary light. The wavelength converting material contains phosphor nano-particles and larger phosphor particles. The phosphor nano-particles prevent transmission of primary light while the larger phosphor particles provide efficient light conversion.

    摘要: An encapsulant containing nanoparticles that improve the heat and UV resistance properties of electroluminescent devices. The nanoparticles that are suspended in the encapsulant may be either oxides or non-oxides and may include SiO2, TiO2, Al2O3, ZrO2, Ti, TiB2, TiC, and TiN. The nanoparticles may range in size from 5 to 165 nm in diameter. The encapsulant containing nanoparticles may be used in an electroluminescent device by being deposited in a concave base cavity to cover a light source, such as a light-emitting diode (“LED”), positioned in the concave base cavity, and may also be applied in the form of a conformal coating that covers the light source. An electroluminescent device utilizing the encapsulant containing nanoparticles and a method of producing such a device is also provided.
