What is the concentration and pH of the Atomfair Single Layer WS2 Quantum Dots Dispersion?
The dispersion is supplied at a concentration of 0.5 mg/mL with a pH range of 8–9, as specified in the technical specifications. This narrow pH range is maintained using LiOH as a stabilizer, ensuring colloidal stability of the quantum dots in water.
What stabilizer is used in the water-based WS2 quantum dot dispersion from Atomfair?
Lithium hydroxide (LiOH) is used as the stabilizer in this aqueous WS2 quantum dot dispersion. The stabilizer maintains the pH between 8 and 9, which is critical for preventing aggregation and preserving the optical properties of the sub-10 nm quantum dots.
This single-layer WS2 quantum dot dispersion in water with sub-10nm size and LiOH stabilizer offers a well-defined aqueous quantum dot system suitable for photoluminescence and optoelectronic studies, but the alkaline pH and fixed concentration impose operational constraints for certain applications.
Positive
- Sub-10nm quantum dot size: Particle size under 10nm enables quantum confinement effects, providing size-dependent optical properties critical for fluorescence and bandgap engineering applications.
- Aqueous dispersion with LiOH stabilizer: Water-based solvent with LiOH stabilizer maintains colloidal stability at pH 8-9, reducing aggregation and allowing direct use in biological or aqueous-phase experiments.
Trade-offs
- Alkaline pH constraint: The pH range of 8-9 from LiOH stabilizer may limit compatibility with pH-sensitive assays, buffers, or materials that require neutral or acidic conditions.
- Fixed concentration of 0.5 mg/mL: The supplied concentration is fixed at 0.5 mg/mL, which may require dilution or concentration steps to match specific experimental needs, introducing additional handling and potential variability.
