日常生活中有机材料有着各种各样的应用，但直到最近有了光子器件才开始探索它们的广泛用途。20多年来，人们普遍知道，当大电压加到有机晶体上时，它就出现电致发光。但对电流激发而言，人们采取了使器件对低电压响应的措施。在激励方面起重要作用的两个事件是80年代初伊斯特? Organic materials have a wide variety of applications in everyday life, but only recently have photonic devices begun to explore their wide range of uses. For more than two decades, it has generally been known that when a large voltage is applied to an organic crystal, it emits electroluminescence. However, in terms of current excitation, people have taken measures to make the device respond to low voltage. Two events that play an important role in motivation are Eastbourne in the early 1980s?
