Cyan emissive sulfur dots with a record high photoluminescence (PL) quantum yield of 49.25% have been successfully prepared a microwave-assisted top-down route. The PL enhancement induced by electrostatic repulsion of sulfite groups and steric hindrance of polyethylene glycol 400 (PEG-400) were investigated for the first time.
通过微波辅助自上而下的方法成功制备了光致发光(PL)量子产率高达49.25%的青色发射硫点。首次研究了亚硫酸根基团的静电排斥和聚乙二醇400(PEG - 400)的空间位阻诱导的PL增强。
