phide. The relatively large physical separation of the electrons and holes means that a nanocrystal with one exciton has a different energy configuration from one with two excitons (Fig. 1b). In this case, a population inversion and optical amplification can occur for nanocrystals containing on average less than one exciton, thus completely avoiding the pitfalls of Auger recombination. Even more impressive is the fact that, under typical pumping conditions for optical gain, the lifetime of the… CONTINUE READING
