有机半导体兰光材料及其电致发光器件的稳定性研究

we have syntheticed several new type of luminescent materials with blue or blue-green emmiting light including LPPP materials,and dioxide（PDPyDP etc）with the properties of carryers transporting for OLED by cooperating with foreign unit.The quantum efficiency and stability of devices have been obviously improved after introducing function group into luminescent materials,optimizating the device structure and improving the organic layer/ metal interface through special heat treatment.A measurement systum about quantum efficiency and other luminescent properties with computer software for OLED has been designed and constructed.We have finished all the subject contents and published ten papers with more high quality.Some technical levels for our device have attained the international level,for example the quantum efficiency is 2.4×10-1 % and the brightness is 3000 cd/m2 for our device in which the LPPP as luminescent layer and the PDPyDP as electron transport layer respectively.

合成并选择具有高荧光效率和稳定性及良好成膜性的有机半导体兰色发光层和载流子输运层材料，在深入研究影响兰色电致发光器件稳定性的主要因素基础上，优化设计合理的器件结构，并用创新的工艺方法，制备出能充分显示出有机材料优越性的兰色器件。由于此类材料选择范围广，成膜工艺和设备简单，随着稳定性的解决，有望取代无机材料获得实用器件。.
