LONG WAVELENGTH LIGHT EMITTING DEVICES WITH HIGH QUANTUM EFFICIENCIES |
摘要 |
Various embodiments of light emitting devices with high quantum efficiencies are described herein. In one embodiment, a light emitting device includes a first contact, a second contact spaced apart from the first contact, and a first active region between the first and second contacts. The first active region is configured to produce a first emission via electroluminescence when a voltage is applied between the first and second contacts, and the first emission having a first center wavelength. The light emitting device also includes a second active region spaced apart from the first active region. The second active region is configured to absorb at least a portion of the first emission and produce a second emission via photoluminescence, and the second emission having a second center wavelength longer than the first center wavelength. |
