Selectivity of Cdte Nanocrystals Synthesized with Sulfhydryl Functionalized Ionic Liquid As Stabilizer in Response to Co2+ and Mn2+
The use of fluorescent semiconductors to detect highly toxic and enriched heavy metal ions in the human body has attracted researchers'interest.Different CdTe nanocrystals were synthesized by using sulfhydryl functionalized ionic liquid as stabilizer,which has good physicochemical properties.By studying the effect of pH value on the fluorescence properties of CdTe nanocrystals,the response of CdTe nanocrystals to Co2+ and Mn2+ was further discussed,and the detection limit and detection range of CdTe nanocrystals for Co2+ and Mn2+ were defined.
