Abstract
Nanoconjugates composed of CdSe-ZnS core-shell nanocrystals and pyrenyl ligands are shown to exhibit a double photoluminescence. Owing to the different response of the two emission signals towards oxygen, the nanocrystals function as high dynamic range ratiometric luminescent O(2) nanosensors.
摘要
由 CdSe-ZnS 核壳纳米晶体和芘基配体组成的纳米复合物表现出双光子荧光。由于两个发射信号对氧的不同响应，纳米晶体作为高动态范围比率荧光 O(2)纳米传感器。
