Application
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.
