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.

Colloidal semiconductor quantum rods have demonstrated many advantageous properties as light emitters such as high quantum yield, tunable emission wavelength, and polarized emission. This makes them an interesting optical gain material for laser applications. We report room-temperature gain lifetimes in
