【摘要】 以8-羟基喹啉铝(Alq3)为主体发光材料,四苯基卟啉(TPP)为掺杂染料,制备了5种不同摩尔掺杂浓度(0.5%、1.0%、1.5%、2.0%、2.5%)的掺杂电致发光器件,考察了掺杂浓度对其器件的电致发光光谱、色度、亮度和发光效率的影响;并结合掺杂器件的发光机理,对实验结果进行了分析和讨论.更多还原

【Abstract】 8-hydroxyquinoline aluminum(Alq3)was used as a host material, while tetraphenylporphyrin (TPP) as the dopant material, we constructed five electroluminescent (EL) devices with different dopant concentration, and studied the influence that the dopant concentration imposed on the EL devices’ electroluminescence spectra, color, max-brightness and max-efficiency. Based on doped EL device’s fluorescence mechanism, such phenomenon was discussed.更多还原
