Abstract
The self-organization of CdSe nanocrystallites into three-dimensional semiconductor quantum dot superiattices (colloidal crystals) is demonstrated. The size and spacing of the dots within the superlattice are controlled with near atomic precision. This control is a result of synthetic advances that provide CdSe nanocrystallites that are monodisperse within the limit of atomic roughness. The methodology is not limited to semiconductor quantum dots but provides general procedures for the preparation and characterization of ordered structures of nanocrystallites from a variety of materials.

Exploring excitations and vibrations in semiconductor nanocrystals through fluorescence and Raman spectroscopy

TL;DR: In this paper, the authors used Förster theory to understand the photoluminescence and vibrational characteristics of QDs, including spectrally-resolved time-correlated single photon counting measurements to understand QD photon lifetime as a function of emission wavelength and low-frequency Raman spectroscopy to measure acoustic phonons in nanocrystal solids.

Space- and time-resolved small angle X-ray scattering to probe assembly of silver nanocrystal superlattices

TL;DR: An in situ space- and time-resolved small angle X-ray scattering measurement is demonstrated that is used to probe the assembly of silver nanocrystal superlattices driven by electric fields and finds that the field induces a size-selection effect that can reduce the polydispersity near the substrate by 21% leading to better quality crystals and resulting in field strength-dependentsuperlattice lattice constants.
