在硅光子学中，光源是关键。在这里，我们展示了一种高效的硅基光源，其中双（2-苯基吡啶）铱（III）乙酰丙酮[（ppy）2 Ir（acac）]磷光体被用作发射器和Au掺杂的n+-Si被用作空穴注入可调阳极。该Si基电致磷光器件在2.9V下实现52.6lm/W的功率效率，这对应于10.0%的功率转换效率，这是足以用于商业用途的水平。
In Si photonics, the light source is a key. Here, we demonstrate a highly efficient Si-based light source, in which bis(2-phenylpyridine) iridium(III) acetylacetonate [(ppy)2Ir(acac)] phosphor is used as emitters and a Au-doped n+-Si is used as a hole-injection adjustable anode. This Si-based electrophosphorescent device achieves a power efficiency of 52.6 lm/W at 2.9 V, which corresponds to a power conversion efficiency of 10.0%, a level that is sufficient for commercial use.
