Effects of transfort layers on luminescence efficiency of organic bilayer devices 輸運層對雙層器件電致發(fā)光效率的影響
A study and comparison of up - conversion luminescence efficiency in four er3 yb3 co - doped glasses 共摻四種玻璃中上轉換發(fā)光效率的比較及研究
This could increase the work function of ito , which would decrease the device threshold voltage and increase the luminescence efficiency consequently 因此,采用氧等離子體處理的ito薄膜作為oled的陽極將降低發(fā)光器件的開啟電壓,提高其發(fā)光效率。
Organic and polymer electroluminescence materials have attracted much interest because of its high luminescence efficiency , full color , processable and so on 有機電致發(fā)光材料由于具有高發(fā)光效率,亮度和顏色可調,易加工成膜等優(yōu)良特性,引起了人們的極大興趣。
In order to clarify the origin of pl and enhance the luminescence efficiency of materials , the study of the relationship between preparation process and pl properties is very important 對制備方法及其工藝參數對薄膜熒光特性影響的研究,不僅可以進一步澄清各熒光帶的起因,而且也是提高材料發(fā)光性能的重要途徑。
