Advantages over Traditional QDs

Made using safe and scalable non-injection synthesis

Free of toxic heavy metals (for example - Cd, Pb) or phosphines

Low self-absorption as a result of a large Stokes shift >300 meV

Bright PL (up to >75% QY) tunable from 550 to 950 nm

Stable PL at elevated temperature in water, air, and various composites

Use and Handling Recommendations

The products are delivered in powder form, and are soluble in non-polar solvents (for example - chloroform, toluene). Standard concentrations are ~5-200 mg/mL for a majority of applications. The dots have been cleaned by dissolution/precipitation three times to develop a dried powder. It is recommended that the product is used within 12 months of receipt.
