CdSe/ZnS Quantum Dots

Quantum dot nanotechnology has successfully entered numerous electronic and biomedical industries. Alfa Chemistry recently announces to provide CdSe/ZnS quantum dots, one of the various subtypes of quantum dots, for customers across the globe.

Owing to their unique properties such as superior photostability, high extinction coefficient and brightness, and large Stokes shift, quantum dots have become very appealing for industries that produce electronics like solar cells, transistors, LEDs, medical imaging, and quantum computing.

“For researchers who are looking for good quality CdSe/ZnS quantum dots, currently we have CdSe ZnS core shell quantum dots and CdSeTe ZnS quantum dots for their choice,” says the Marketing Chief of Alfa Chemistry. “And as time goes by, we’ll keep adding more to this category.”

CdSe ZnS Core Shell Quantum Dots

With a purity of 99+%, the CdSe ZnS (short for cadmium selenide zinc sulfide) core shell quantum dots has wonderful optical properties, featuring a ZnS coating that helps to protect and stabilize the unique optical properties of the CdSe core from potentially damaging environments, and at the same time reducing surface trap states and improving performance. The ZnS shell renders bright and stable luminescence and their stable nature allows further surface-chemistry manipulation.

The CdSe ZnS core shell quantum dots have potential applications in fields like imaging and display research, and surface chemistry.

CdSeTe ZnS Quantum Dots

With a purity of 99.99% and in the form of liquid, CdSeTe ZnS quantum dots also behaves well in many aspects such as the high quantum yield of exciton luminescence, and the long photo stability and the rearrangement of the exciton luminescence band in a wide spectrum range. All makes them potentially applicable in photovoltaic and laser devices, thin-film transistors, light-emitting diodes and luminescent labels in biology and medicine.

“Besides CdSe/ZnS quantum dots, we also offer many other forms of quantum dots, including alloyed quantum dots, cadmium free quantum dots, carbon dots, CdS/ZnS quantum dots, InP ZnS quantum dots, PbSe/PbS quantum dots, upconverting nanoparticles (UCNPs), ZnSe/ZnS quantum dots, and more,” the Marketing Chief further explains.
