The effect of different ratios of PVK on the device characteristics is also studied.
文章同时比较了几种不同PVK掺杂浓度对于器件性能的影响。
When TPP was doped into PVK, no significant energy transfer was observed and pure red emission was gotten in EL.
在TPP掺杂pvk的复合体系中，并没有观察到两者明显的能量传递，但掺杂体系的电致发光为纯的红光发射。
Poly (N-vinyl carbazole) was modified to prepare azo-PVK by post-azo-coupling reaction with diazo salt as raw material using phase-transfer catalysts.
我们以聚乙烯咔唑为偶合组分，和发色基团对硝基苯重氮盐在相转移催化剂存在下，采用后重氮偶合方法，制备出偶氮化聚乙烯咔唑。
The molar mass proportion of PVK and diazo salt is 1:4. Diazo salt was divided into several parts and added into solution in batches at room temperature to react for 96 hours.
聚乙烯咔唑和重氮盐摩尔质量比1：4，重氮盐按分批加入方式加入到反应液中，反应时间96小时，反应温度室温。
