TCTA对红绿磷光有机电致发光器件发光层激子的调控作用
Effect of TCTA Layer on Exciton Positions of Red and Green Phosphorescent Organic Light Emitting Diodes
摘要
Abstract
Red and green phosphorescent organic light emitting diodes were fabricated,utilizing GIr1 and R-4B (novel red and green) phosphorescent materials.Device structure was ITO/MoO3 (50 nm)/NPB(40 nm)/TCTA(10 nm)/CBP∶ 14％ GIr1 (30 nm)/TCTA(x)/CBP∶ 2％ R-4B(10 nm)/BCP(10 nm)/Alq3(40 nm)/LiF(1 nm)/ Al(1O0 nm).The luminescent properties were studied by inserting different thickness of TCTA (regulation of carrier) spacer layer between red and green emitting layer to adjust the distribution of carriers and excitons.The results showed that the optimum performance of OLED was achieved when the thickness of TCTA spacer layer is 1 nm.The maximum the device performance reached 13.72 cd/A,0.509 mA/cm2 and 69.91 cd/m2 at 6 V.While for 0 nm (none spacer),the device performance reached 11.67 cd/A,1.848 mA/cm2 and 215.7 cd/m2 at 6 V.关键词
