| 摘要 |
A high quality white light emitting device suitable for miniaturization. The white light emitting device according to the present invention includes a substrate and a light emitting structure composed of an n-semiconductor layer, an active layer and a p-semiconductor layer. The light emission structure emits first emission light. The white light emitting device also includes a wavelength-converting film for absorbing and converting the first emission light to second emission light of another wavelength. The wavelength-converting film is made of europium-silicate. |
