Abstract

Narrow luminescence lines from self-assembled CdSe quantum dots (QDs) are studied at room temperature by using time-resolved photoluminescence spectroscopy. The narrowest line of the luminescence has a full width at half maximum of 2.1 meV at room temperature. The narrow luminescence lines are mainly the contribution of CdSe QDs with a longer recombination lifetime to the luminescence.
