General description

Reactive group: Octadecylamine.

Application

Highly purified CdSe/ZnS quantum dots with an octadecylamine surface contain extremely low free organic ligands and impurities. They are well suited for display, solid state lighting and solar cell applications. They can be used as an electroluminescence emitter in quantum dot based LEDs or embedded in a polymer matrix as the backlight of an LCD display. CdSe/ZnS quantum dots in solid form can be dispersed in most non-polar organic solvents such as toluene, chloroform, and hexane.
