Abstract :
Studies of Auger recombination in size/shape-controlled CdSe nanoparticles reveal that elongated nanocrystals provide almost independent control of the emission wavelength (diameter) and the Auger recombination rate (length). The results suggest that shape control may be the key to developing practical lasing applications.
