Application

CdSe/ZnS core/shell nanocrystals in solid form are highly purified quantum dots. They can be dispersed in most non-polar organic solvents such as toluene, chloroform, hexane, etc. With very low organic impurity, these quantum dots are specifically designed as emitters for optoelectronic applications such as display and solid state lighting.

Protocol to make QD solutions (dispersing QDs into solutions):

1. Weigh desired amount of the quantum dot powder and put it in a glass vial;
2. Add desired amount of the solvent, i.e. toluene, chloroform, hexane, etc. (mostly non-polar organic solvents) in the vial and shake the vial;
3. If there is any solid left in the vial after shaking, sonicate the vial for 30~60 seconds to get the quantum dot powder well dispersed. If required dilute the solution further.

Material has a shelf life of around 3 years if stored properly. Store at room temperature (4-25 °C); do not freeze. Should not be exposed to extreme temperatures.

  2. What is the particle density for product 790192, CdSe/ZnS core-shell quantum dots?

    1 answer
    1. The particle density is not determined for this product.

      Helpful?

  3. What is the molecular weight of CdSe/ZnS core-shell type quantum dots, and what is the recommended method for their dissolution?

    1 answer
    1. The molecular weight information for CdSe/ZnS core-shell type quantum dots is typically not provided in the QD field, as it can be calculated based on the quantum effect via size. The recommended solvents for dissolving CdSe/ZnS core-shell type quantum dots include chloroform, toluene, xylene, and THF. The procedure for dissolution involves adding the solvent to the QD solid, shaking it for 3 minutes, and sonication for 20 seconds if the QDs are not completely dispersed. If toluene is the solvent, any grade of toluene can be used. No specific equipment is needed for dissolving CdSe/ZnS core-shell type quantum dots; shaking the vial is sufficient.
