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.[1][2][3]

Owing to their narrow bright emission band, broad size-tunable emission wavelength, superior photostability, and excellent flexible-substrate compatibility, light-emitting diodes based on quantum dots (QD-LEDs) are currently under intensive research and development for multiple consumer applications including flat-panel displays and flat

We report a multilayer solution-processed blue light-emitting diode based on colloidal core/shell CdS/ZnS nanocrystal quantum dots (QDs). At a low-operating voltage of 5.5 V, the device emits spectrally pure blue radiation at 460 nm with a narrow full-width-at-half-maximum bandwidth of

What does "solid" mean? Is it a "block" of quantum dots? Is it quantum dots contained in a block of some material? If so, what material? Is there someone I can talk to about your quantum dots?
1 answer-
"Solid" means 900212 (CdSe/ZnS core-shell type quantum dots) is in powder form. There is no block to separate the quantum dots. The octadecylamine reactive group on the surface may help to re-disperse the powder into solution. Please contact the local technical service for more details.
