The reason to cause this phenomenon is due to the change of electric field in the blue oled to induce the probality of the carrier shifted and the hole - electron recombination zone changed , which was a possible alternative to achieve color display . 3 ) device with the structure of ito / npb / adn : balq3 / alq3 / mg : ag was fabricated . when the balq3 dopant concentration was about 25 mol % , a high performance devcie with luminous efficiency of 1 . 0 lm / w , the peak of emission spectrum at 440 nm , the cie coordinate at ( 0 . 18 , 0 . 15 ) , and half lifetime of unencapsulated device about 950 hrs was achieved
導(dǎo)致本現(xiàn)象的原因是由于各有機(jī)層電場強(qiáng)度的變化影響了空穴和電子的隧穿幾率,從而導(dǎo)致載流子的復(fù)合區(qū)域發(fā)生改變而發(fā)出不同顏色的光; 3 )制備了結(jié)構(gòu)為ito / npb / adn : balq3 / alq3 / mg : ag的藍(lán)光oled ,空穴阻擋材料balq3的摻入顯著影響了oled的光電性能,當(dāng)balq3的摻雜濃度為25mol %時, oled的發(fā)光效率為1 . 0lm / w ,發(fā)光光譜的峰值為440nm ,色純度為( 0 . 18 , 0 . 15 ) ,未封裝器件的半衰期達(dá)到了950小時; 4 )在藍(lán)光材料adn中摻雜npb 、 balq3和tbp三種材料時,不僅改善了器件的發(fā)光亮度和色純度,而且提高了器件的發(fā)光效率和壽命。
