Descrizione generale

Reactive group: Octadecylamine.

Applicazioni

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

Recent Advances in the Use of Cadmiumfree Quantum Dots for Bioimaging

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.
