Product Features
Excellent optical performance: Sulfur quantum dots exhibit unique fluorescence properties, such as large Stokes shift, good stability, and emission peaks that do not vary with excitation wavelength.
Its quantum yield can reach 3.8%, and it has good dispersibility and optical stability in water.
Good biocompatibility: Sulfur quantum dots are widely used in cell imaging and biomedical research due to their low toxicity, no heavy metal pollution, and good biocompatibility.
Application Fields
Fluorescent probe detection: Sulfur quantum dots, as fluorescent probes, can detect heavy metal ions such as PB (II) and BI (III) with low detection limits and good sensitivity.
Cell imaging: In the biomedical field, sulfur quantum dots are used for cell labeling and imaging. Due to their high fluorescence intensity and good biocompatibility, they can clearly observe the internal structure and dynamic processes of cells.
Optoelectronic conversion: The application of sulfur quantum dots in optoelectronic conversion devices has also received widespread attention, and their excellent optical properties make them ideal materials for optoelectronic devices.
Chemical catalysis: Sulfur quantum dots exhibit excellent performance in chemical catalytic reactions, and their unique optical properties and high stability make them of great value in catalyst design and optimization.
Environmental sensing: Sulfur quantum dots have also been widely used in environmental monitoring and pollutant detection, and their high sensitivity and specificity make them ideal sensing materials.
Related Information
Attention: Sulfur Quantum Dots cannot be mixed with acidic medium.Before dilution, best doing some dialysis treatment, dialysis the high concentration of alkali and other ions in the sample with low concentration of alkali dialysis, and then diluted. The sample can be diluted directly in alkaline solvent if we cannot do dialysis treatment. 0.1M NaOH or KOH solution is recommended to be diluted.
The sulfur quantum dots have large aggregates (20 to 80nm), which are composed of small nanoparticles smaller than 5nm.
