Abstract
The rational design of semiconductor nanocrystal populations requires control of their emission linewidths,which are dictated by interparticle inhomogeneities and single-nanocrystal spectral linewidths. To date,research efforts have concentrated on minimizing the ensemble emission linewidths, however there is littleknowledge about the synthetic parameters dictating single-nanocrystal linewidths. In this direction, wepresent a flow-based system coupled with an optical interferometry setup for the extraction of singlenanocrystal properties. The platform has the ability to synthesize nanocrystals at high temperature<300°C, adjust the particle concentration after synthesis and extract ensemble-averaged single nanocrystalemission linewidths using flow photon-correlation Fourier spectroscopy.
