CdSe/CdS/ZnS
Strem offers the following Quantum Dots
Core: CdSe
Core/Shell: CdSe/CdS
Core/Shell/Shell: CdSe/CdS/ZnS
The CdSe core is highly uniform with a narrow particle size distribution (±10%). The CdS shell is less than 1nm and stabilizes the core. The second shell of ZnS provides additional stability and is 1-2 nm thick.
Product characteristics:
High Quantum Yield- Longer term stability
- Scalability (produced via continuous flow)
- High batch-to-batch reproducibility (TEM available for each lot)
- Emission range 500-650nm
- Homogeneous dispersions in different non-polar solvents possible
- Flexibility for ink or composite preparation
