1、引言目前,对蒽单晶电致发光的研究比较活跃,用并四苯、并五苯苝和对蒽掺杂,观察到了主(蒽)和宾(掺杂剂)分子的 EL 发射。适当地选择掺杂剂,以及改变掺杂浓度可以控制 EL 的光谱分布和强度,例如使光谱由蓝区移向红区。因此,使用掺杂的蒽晶 1. Introduction At present, the research on the electroluminescence of anthracene single crystal is relatively active. The EL emission of the main (anthracene) and guest (dopant) molecules is observed by doping with tetracene, pentacene and perylene. Appropriate choice of dopant, as well as varying the doping concentration, can control the spectral distribution and intensity of the EL, for example by moving the spectrum from blue to red. Therefore, doped anthracene crystals are used
