How does the emission wavelength of 460 nm for CdZnS/ZnS quantum dots relate to their specified excitation at 365 nm?
The emission at 460 nm (blue) results from excitation at 365 nm (UV), indicating a Stokes shift characteristic of CdZnS/ZnS core/shell quantum dots. This combination is explicitly specified in the product configuration (Excitation: 365 nm; Emission: 460 nm) and reflects the material's bandgap and size-dependent fluorescence.
What solvents are compatible with CdZnS/ZnS quantum dots for solution-based applications?
The product is supplied in toluene and n-heptane as solvents, with cyclohexane listed as an additional specification option (Solvent: toluene, n-heptane; Specification: cyclohexane). These non-polar organic solvents make the quantum dots suitable for hydrophobic environments and common deposition techniques like spin-coating.
What safety precautions are required when handling CdZnS/ZnS quantum dot solutions?
The material contains cadmium (Cd) as part of its composition (CdZnS/ZnS) and is dissolved in flammable organic solvents (toluene/n-heptane). Handling must be conducted in a chemical fume hood with appropriate PPE, and waste disposal should follow hazardous material protocols as per laboratory safety guidelines.
CdZnS/ZnS core/shell quantum dots at 3 mg/mL in toluene/n-heptane with 365 nm excitation and 460 nm emission, supplied as a 10 mL solution for fluorescence-based research applications.
Positive
- Well-defined Stokes shift for multiplexing: Excitation at 365 nm and emission at 460 nm provide a large spectral separation, enabling clean signal discrimination in multi-fluorophore assays or imaging workflows.
- Ready-to-use colloidal dispersion: Supplied at a fixed concentration of 3 mg/mL in toluene/n-heptane, eliminating the need for in-house dispersion preparation and reducing batch-to-batch variability.
Trade-offs
- Flammable organic solvent handling required: The toluene/n-heptane solvent mixture is flammable and toxic; use in a fume hood with appropriate personal protective equipment and proper waste disposal protocols is mandatory.
- Fixed concentration limits dilution flexibility: The supplied concentration is fixed at 3 mg/mL; users requiring lower concentrations must dilute, which may alter solvent composition and potentially affect colloidal stability or optical properties.
