研究目的
Investigating the synthesis of CdSe/ZnS@HPU-2 composites for highly sensitive and multicolor fluorescence response to Fe3+.
研究成果
The hybrid material QDs@HPU-2 was successfully demonstrated as a sensitive probe for Fe3+, showing a multicolor fluorescence response. This combination of Cd-MOF and CdSe/ZnS QDs properties makes the sensor suitable for practical applications with observable color changes.
研究不足
The study's limitations include the need for further optimization of the probe's sensitivity and selectivity, as well as potential environmental effects in complex samples.
1：Experimental Design and Method Selection:
The study involved the hybridization of a three-dimensional framework with CdSe/ZnS quantum dots (QDs)-doped silica nanoparticles to create a dual-emission probe for Fe3+.
2：3+. Sample Selection and Data Sources:
2. Sample Selection and Data Sources: The samples included CdSe/ZnS QDs and a Cd-based MOF.
3：List of Experimental Equipment and Materials:
Equipment used included a Siemens Smart CCD single-crystal X-ray diffractometer, FLASH EA 1112 elemental analyzer, PANalytical X’Pert PRO diffractometer, Netzsch STA 449C thermal analyzer, and Hitachi F-4500 Fluorescence Spectrophotometer. Materials included CdI2, H2DPTMIA, and various solvents.
4：Experimental Procedures and Operational Workflow:
