Claims16
A phosphor composition, comprising:
- a phosphor nucleus, and
- a hydrophobic layer bonded on a surface of the phosphor nucleus and consisting of an organic compound with a hydrophobic functional group, wherein the organic compound consists of alkylsilyl halide.
A light emitting diode (LED) device, comprising:
- an LED chip for emitting a first light with wavelength λ1;
- and
- a phosphor composition comprising a phosphor nucleus and a hydrophobic layer, wherein the hydrophobic layer is bonded on a surface of the phosphor nucleus and consists of an organic compound with a hydrophobic functional group, wherein the organic compound consists of alkylsilyl halide, and the phosphor composition, being irradiated by the first light with wavelength λ1, emits a second light with wavelength λ2 mixed with the first light with wavelength λ1 to form a white light spectrum, and λ2>λ1.
