Abstract

Through harvesting of the increased Stokes shift of CdS QDs via Cu-doping, the concentration-quenching or aggregation-quenching of CdS QDs was largely alleviated. A dually-enriched strategy with both polyvinylpyrrolidone (PVP) twisting and SiO2 loading was developed for generating a highly luminescent doped-dots (d-dots) assembly for improved cell imaging.

摘要

通过铜掺杂收获硫化镉量子点增加的斯托克斯位移,很大程度上缓解了硫化镉量子点的浓度猝灭或聚集猝灭。开发了一种聚乙烯吡咯烷酮(PVP)扭曲和二氧化硅负载的双重富集策略,以生成用于改善细胞成像的高发光掺杂点(d-点)组件。
