解釋
第三代環保清洗劑正溴丙烷-
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
導致本現象的原因是由於各有機層電場強度的變化影響了空穴和電子的隧穿幾率，從而導致載流子的復合區域發生改變而發出不同顏色的光; 3 ）制備了結構為ito / npb / adn : balq3 / alq3 / mg : ag的藍光oled ，空穴阻擋材料balq3的摻入顯著影響了oled的光電性能，當balq3的摻雜濃度為25mol %時， oled的發光效率為1 . 0lm / w ，發光光譜的峰值為440nm ，色純度為（ 0 . 18 ， 0 . 15 ） ，未封裝器件的半衰期達到了950小時; 4 ）在藍光材料adn中摻雜npb 、 balq3和tbp三種材料時，不僅改善了器件的發光亮度和色純度，而且提高了器件的發光效率和壽命。 -
Measured results showed that the dl - a device with its structure as following ito / npb / alq / mg : ag was far more superior to sl device with the structure of ito / alq / mg : ag because the dl - a device better balanced energy band between each each layer and the mobility of carriers ( electrons and holes ), which led to the combination of carriers taking place in the bulk of emitter and avoided the excitons being eliminated by the electrodes which easily occurs in sl devices. as to the doped devices, measurements demonstrated an excellent device with its maximum brightness was 25000cd / m2
研究結果表明， dl - a型雙層結構器件ito / npb / alq / mg : ag的各項性能指標明顯優于單層器件ito / alq / mg : ag ，因為前者有更好的載流子遷移率匹配以及能帶匹配，因此平衡了復合的載流子數目，並且能將復合區有效控制在發光層內部，有效避免了表面的大量缺陷以及電極猝滅效應，提高了載流子的復合效率，從而提高了器件的發光性能。 -
4 ) npb, balq3 and tbp as dopants were doped into adn matrix
最後，研究了以rubrene作為輔助摻雜劑的有機紅光發光器件，由於使用 -
First, the devcice with the structure of ito / npb ( 15nm ) / alq3 ( x ) / mg : ag was prepared by thermal deposition in high vacuum. the influence of tris - ( 8 - hydroxyquinoline ) aluminum ( alq3 ) film thickness on the dvicec performance was examined
首先，制備了結構為ito / npb / alq3 / mg : ag的雙層綠色發光器件，並且研究了alq3的發光層的膜厚度對綠光器件的光電性能的影響，優化了alq3的薄膜厚度。
