论文摘要
尽管白炽灯源通常在空间上是不一致的，但已知一段时间以来，热源的适当设计可以改变其空间相干性。一个自然的问题是，是否可以将此分析扩展到电致发光和光致发光。需要一个理论框架来探索这些属性。在本文中，我们将有效的一般连贯吸收关系扩展到两个非均衡情况：发光体和动脉热体。然后，我们使用此关系来分析等温和肛门热病例之间的差异，并研究电发光源的近场发射。
Despite the fact that incandescent sources are usually spatially incoherent, it has been known for some time that a proper design of a thermal source can modify its spatial coherence. A natural question is whether it is possible to extend this analysis to electroluminescence and photoluminescence. A theoretical framework is needed to explore these properties. In this paper, we extend a general coherence-absorption relation valid at equilibrium to two non-equilibrium cases: luminescent bodies and anisothermal bodies. We then use this relation to analyse the differences between the isothermal and anisothermal cases and to study the near-field emission of an electroluminescent source.
