摘要

We present the results of micro-photoluminescence experiments on individualCdSe quantum dots. The use of a novel jitter correlation technique in these samples allowedus to identify individual dots and hence label transitions in these dots. We dicuss the bindingenergies, dynamics and lineshapes of excitons, trions and biexcitons thus identified. We finda biexciton binding energy of 20 - 25 meV and a trion binding energy of 15 - 22 meV. Wealso give data on the lifetimes of these states and show evidence for a spin-relaxation limitedenergy relaxation of the trion.
