Nanodispersed Materials
A number of Cd, Zn or Pb chalcogenides, surface derivatised sub-micrometric and nano-metricmaterials, especially from simple single molecule precursors, have been prepared.


The figure below is a HRTEM (high resolution transmission electron micrograph) image of a quantum dot of CdSe.(4, 8, 14)
The figure below is a series of images illustrating three different sizes of PbS; 1) Naturally occurring PbS (photograph), 2) SEM (scanning electron micrograph) of PbS deposited film, 3) HRTEM (high resolution transmission electron micrograph) of nanocrystals of PbS.(15)
