conditions, the three main PL emissions constitute a form of white light. We fabricated high-brightness, broad-spectrum, white-light organic light-emitting diodes, incorporating a single emission layer of the blue-light-emitting material TPSBF, which comprises four pyrene units linked to a spirobifluorene core. An organic light-emitting device with the configuration indium tin oxide (170 nm)/4,4',4''
我们描述了2,2',7,7'-四(pyren-1-yl)-9,9'-螺双芴(TPSBF)的形态,光致发光(PL)和电致发光特性如何与其膜厚度相关联,以及在优化条件下,三种主要PL辐射如何构成白光形式。我们制造了高亮度,广谱,白光有机发光二极管,其中结合了蓝光发射材料TPSBF的单个发射层,该发射层包括连接到螺二芴核的四个pyr单元。具有氧化铟锡(170 nm)/ 4,4',4''-三[N-(2-萘基)-N-苯基氨基]三苯胺(15 nm)/ 4,4'构型的有机发光器件-双[N-(1-萘基)-N-苯基氨基]联苯(65 nm)/ TPSBF(50 nm)/三(8-羟基喹啉)铝(30 nm)/ LiF(0。
