Core Type Quantum Dots Are Now Available at Alfa Chemistry

Posted by Tylor on August 27th, 2021

Quantum dots have become very appealing for the manufacturing of electronic devices, solar cells, laser diodes, medical imaging devices, and numerous other optoelectronic products. In response to the growing demand from both market and research circles, earlier this month Alfa Chemistry announces to provide core type quantum dots, which is one of the various forms of quantum dots.

Core-type quantum dots are composed of a single material, typically a metallic chalcogenide such as cadmium telluride or lead sulfide. Quantum dots can be manufactured in various forms, and alloyed quantum dots, cadmium free quantum dots, carbon dots, CdS/ZnS quantum dots, CdSe/ZnS quantum dots, InP ZnS quantum dots, PbSe/PbS quantum dots, upconverting nanoparticles (UCNPs), ZnSe/ZnS quantum dots are all commonly seen quantum dot types.

“Quantum dots have many advantages such as bright, pure colors, ability to emit rainbow of colors, longer lifetimes and high extinction coefficient, so they are warmly welcomed in optical applications. In addition, their small size also allows them to go anywhere in the body, making them suitable for different bio-medical applications like medical imaging, biosensors,” says the Marketing Chief of Alfa Chemistry.

A wide range of core type quantum dots are now available at Alfa Chemistry. Below are some of them:

Lead Sulphide-MPA-COOH Quantum Dots, Lead Sulphide-PEG-COOH Quantum Dots, Lead Sulphide-PEG-NH? Quantum Dots, CdS/ZnS core-shell type quantum dots lyophilized (fluorescence λem 400 nm, solid), CdS/ZnS core-shell type quantum dots oleic acid functionalized (fluorescence λem 425 nm, 5 mg/mL in toluene), CdSe/CdS core-shell type quantum rods (fluorescence λem 530 nm, 5 mg/mL in hexane), CdSeS/ZnS alloyed quantum dots (fluorescence λem 450 nm, 6 nm diameter, 1 mg/mL in toluene), PbS core-type quantum dots oleic acid coated (fluorescence λ) and many more.
