What is the concentration and pH of the WS2 quantum dot dispersion, and how does the LiOH stabilizer maintain stability?
The dispersion has a concentration of 0.5 mg/mL and a pH of 8–9, maintained by the LiOH stabilizer. This alkaline pH and stabilizer are specified to prevent aggregation and ensure colloidal stability of the single-layer WS2 quantum dots in water.
Can this water-based WS2 quantum dot dispersion be used directly in aqueous-phase biological or photocatalytic applications?
Yes, the solvent is deionized water, making it directly compatible with aqueous environments. However, the pH of 8–9 and the presence of LiOH stabilizer may require pH adjustment or buffer compatibility checks for sensitive biological or photocatalytic systems.
This Single Layer WS2 Quantum Dots Dispersion (<10nm, water, 100mL) is a research-grade product with a concentration of 0.5 mg/mL, stabilized with LiOH at pH 8-9, suitable for photoluminescence and optoelectronic studies requiring aqueous-phase quantum dots.
Positive
- Sub-10 nm particle size: The <10 nm size range provides strong quantum confinement effects, enabling size-tunable optical properties for fluorescence and excitonic studies in aqueous environments.
- Aqueous dispersion with stabilizer: Water-based solvent with LiOH stabilizer at pH 8-9 ensures colloidal stability and compatibility with biological or hydrophilic assay systems, reducing aggregation risk during handling.
Trade-offs
- Low concentration limits applications: At 0.5 mg/mL, the dispersion is dilute, requiring larger volumes or concentration steps for experiments needing higher quantum dot density, such as thin-film deposition or high-sensitivity sensing.
- Alkaline pH storage requirement: The pH 8-9 range necessitates careful storage and handling to avoid pH drift or precipitation, and may not be compatible with acidic or neutral buffer systems without adjustment.
