Effects of transfort layers on luminescence efficiency of organic bilayer devices 输运层对双层器件电致发光效率的影响
A study and comparison of up - conversion luminescence efficiency in four er3 yb3 co - doped glasses 共掺四种玻璃中上转换发光效率的比较及研究
This could increase the work function of ito , which would decrease the device threshold voltage and increase the luminescence efficiency consequently 因此,采用氧等离子体处理的ito薄膜作为oled的阳极将降低发光器件的开启电压,提高其发光效率。
Organic and polymer electroluminescence materials have attracted much interest because of its high luminescence efficiency , full color , processable and so on 有机电致发光材料由于具有高发光效率,亮度和颜色可调,易加工成膜等优良特性,引起了人们的极大兴趣。
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 对制备方法及其工艺参数对薄膜荧光特性影响的研究,不仅可以进一步澄清各荧光带的起因,而且也是提高材料发光性能的重要途径。
