QSP is a group of highly purified CdSe/ZnS quantum dots in solid form. Their surface ligand is octadecylamine. They can be dispersed in most organic solvents such as toluene, chloroform, hexane, etc. With very low number of free organic ligand and very low organic impurity, these quantum dots are specifically designed as emitters for optoelectronic applications such as LEDs. Please find the information about using these quantum dots for the fabrication of QDLEDs in our related publications.
