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于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。

The electronic temperature , intensities of all lines and continuous spectra gradually increased with the increment of laser energy , and they got to maximum at different laser energy . our results of copper and aluminum show that there are possibly different thresholds of laser energy to electronic temperature and intensities of emission spectra of laser ablated plasma . at the different environmental gas pressure , spatial emission intensity distribution is explained by the competition among “ heat reservoir effect “ , “ confined effect “ and “ s hadow effect “ 認為cu等離子體羽的發光機制是由電子與粒子的碰撞傳能、電子與離子的復合形成的；隨激光能量的增加， cu等離子體特征輻射(分立譜) 、連續背景輻射(連續譜) 、電子溫度都出現最大值；結合對al的實驗結果說明：激光燒蝕金屬產生的等離子體，其特征輻射、連續輻射、電子溫度可能都存在一定的能量閾值；背景氣壓對激光燒蝕等離子體譜線的影響，其機理可以認為是“熱庫效應” 、 “約束效應”及“陰影效應”相互競爭的綜合結果。

When x is above 1 . 3 % , the emission spectra are strongly broadened and do not show any well - defined features , and their peak positions shift to lower energies correspondingly with increasing x . the large band - gap bowing of gap1 - xnx alloy is induced by the impurity band formation due to the intercenter interaction 對中心發光的nn3束縛激子的零聲子線及其聲子伴線，并得到了nn3的所有聲子伴線( l0 、 la 、 ta )的s因子在約20k卜50k范圍內與溫度的關系。
