摘要：
A light emitting device comprising a light emitting component that emits light with a first peak wavelength, and at least one sintered ceramic plate over the light emitting component is described. The at least one sintered ceramic plate is capable of absorbing at least a portion of the light emitted from said light emitting component and emitting light of a second peak wavelength, and has a total light transmittance at the second peak wavelength of greater than about 40%. A method for improving the luminance intensity of a light emitting device comprising providing a light emitting component and positioning at least one translucent sintered ceramic plate described above over the light emitting component is also disclosed.
