How does the particle size range of 2–5 nm influence the fluorescence emission wavelength of these carbon quantum dots?
The product description reports a particle size of 2–5 nm and yellow fluorescence, but does not provide the emission wavelength or quantum yield. Carbon quantum dots in this size range typically exhibit size-dependent photoluminescence, with smaller particles emitting at shorter wavelengths. The yellow emission suggests a specific bandgap, but without spectral data, the exact wavelength cannot be determined from this datasheet.
Can this water-soluble carbon quantum dot dispersion be used in non-aqueous solvents or polymer matrices?
The product is supplied as a dispersion in water, as stated in the solvent parameter. It is water-soluble by design. The source does not specify compatibility with organic solvents or polymer matrices. Researchers should test miscibility in their target system, as the aqueous dispersion may not be directly compatible with hydrophobic environments without additional surface modification.
What is the recommended shelf life and storage temperature for the 1 mg/mL carbon quantum dot dispersion?
The product page does not provide a shelf life or storage temperature. It is supplied as a research-grade dispersion in a 50 mL package. The manufacturer recommends confirming concentration, solvent, and package size before use, and matching the dispersion format to the intended storage practice. Users should refer to standard protocols for colloidal quantum dots and avoid repeated freeze-thaw cycles.
This water-soluble yellow fluorescence carbon quantum dot dispersion (SKU AF-NM-Q-CQDY-L1M5-SGEV, model AF-CQDYL1M50ML) provides a 1 mg/mL aqueous dispersion with 2–5 nm particle size, suitable for fluorescence-based bioimaging and sensing. Its water-only solvent and inherent particle size range require users to verify compatibility with organic-phase workflows and characterize batch consistency for quantitative applications.
Positive
- Aqueous compatibility for biological workflows: Water-based dispersion eliminates organic solvent handling, enabling direct integration into aqueous-phase synthesis, cell culture, or bioassay protocols without additional solubilization steps.
- Nanoscale particle size range: Particle size of 2–5 nm provides quantum confinement effects yielding size-dependent fluorescence, suitable for multiplexed labeling or high-resolution imaging applications.
Trade-offs
- Single solvent limitation: This product is available only as a water dispersion; applications requiring organic solvent compatibility or non-aqueous processing require sourcing alternative formulations.
- Batch-to-batch particle size variation: The 2–5 nm specification indicates a size range; precise optical properties may vary between batches, and characterization (e.g., TEM, DLS) is recommended for quantitative assays.
