Application

CdSe/CdS quantum rods possess excellent optoelectronic properties such as tunable emission wavelength, high extinction coefficient, polarized emission, enhanced quantum yield and exhibit an order of magnitude higher brightness. These outstanding properties make the CdSe/CdS nanorods suitable for applications such as displays, solid state lighting (LED) and lasers as these require strong fluorescence.

Caution

Handle under nitrogen/argon under subdued light.
Do not freeze.
