Anomalous temperature dependence of the the spin-flip thermalization time between the dark and bright exciton states in silicon nanocrystals
Brian Julsgaard, Ying-Wei Lu, Peter Balling +1
Silicon nanocrystals are studied by time-resolved fluorescence spectroscopy. After laser excitation the bright and dark exciton ground state levels are populated at random, but sub…

Decay dynamics of quantum dots influenced by the local density of optical states of two-dimensional photonic crystal membranes
B. Julsgaard, J. Johansen, S. Stobbe +5
We have performed time-resolved spectroscopy on InAs quantum dot ensembles in photonic crystal membranes. The influence of the photonic crystal is investigated by varying the latti…
