Light-emitting device with narrow dominant wavelength distribution and method of making the same |
摘要 |
This application discloses a light-emitting device with narrow dominant wavelength distribution and a method of making the same. The light-emitting device with narrow dominant wavelength distribution at least includes a substrate, a plurality of light-emitting stacked layers on the substrate, and a plurality of wavelength transforming layers on the light-emitting stacked layers, wherein the light-emitting stacked layer emits a first light with a first dominant wavelength variation; the wavelength transforming layer absorbs the first light and converts the first light into the second light with a second dominant wavelength variation; and the first dominant wavelength variation is larger than the second dominant wavelength variation. |

1. A light-emitting device, comprising:
a substrate; a plurality of light-emitting stacked layers on the substrate, wherein each of the plurality of light-emitting stacked layers emits a first light, and the first lights emitted by the plurality of light-emitting stacked layers have a first dominant wavelength variation; and a plurality of wavelength transforming layers covering the plurality of light-emitting stacked layers, wherein each of the plurality of wavelength transforming layers absorbs the first light and emits a second light, and the second lights emitted by the plurality of wavelength transforming layers have a second dominant wavelength variation smaller than the first dominant wavelength variation. |
