    • 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.
    • 本文描述了具有高量子效率的发光器件的各种实施例。 在一个实施例中,发光器件包括第一触点,与第一触点间隔开的第二触点,以及第一和第二触点之间的第一有源区。 第一有源区域被配置为当在第一和第二触点之间施加电压并且第一发射具有第一中心波长时通过电致发光产生第一发射。 发光器件还包括与第一有源区间隔开的第二有源区。 第二有源区被配置为吸收第一发射的至少一部分并通过光致发光产生第二发射,并且第二发射具有比第一中心波长长的第二中心波长。
