What is the particle size and concentration of the Atomfair WS2 quantum dot dispersion?
The dispersion contains WS2 quantum dots with a size of <10 nm at a concentration of 0.5 mg/mL, as stated in the technical specifications. The package size is 200 mL.
What solvent and stabilizer are used in the Atomfair WS2 quantum dot dispersion?
The solvent is water and the stabilizer is lithium hydroxide (LiOH), resulting in a pH of 8-9. This water-based formulation is suitable for aqueous-phase applications.
This Single Layer WS2 Quantum Dots Dispersion provides sub-10 nm particle size in aqueous medium at 0.5 mg/mL concentration, stabilized with LiOH at pH 8-9, suitable for photoluminescence and optoelectronic studies requiring monodisperse transition metal dichalcogenide quantum dots.
Positive
- Sub-10 nm particle size: The <10 nm diameter ensures quantum confinement effects typical of monolayer WS2, enabling size-dependent optical and electronic properties for fundamental spectroscopy or device prototyping.
- Aqueous dispersion with pH control: Water-based solvent with LiOH stabilizer maintains pH 8-9, providing colloidal stability and compatibility with biological or aqueous-phase processing workflows without organic solvent handling.
Trade-offs
- Low concentration limits throughput: At 0.5 mg/mL, the 200 mL volume yields only 100 mg total solids, requiring larger volumes or concentration steps for applications needing higher mass loading or film deposition.
- Alkaline pH requires compatibility check: The pH 8-9 range may cause aggregation or degradation when mixed with acidic reagents or certain biomolecules, necessitating buffer matching or pH adjustment prior to use.
