During the last two decades, a great deal of attention has been focused on the optoelectronic properties of nanostructured semiconductors or Quantum Dots (QDs). QDs absorb over a broad range and have photoluminescence emission over a narrow range which can be tuned depending on the material from which the QD is made and the size of the QD. The applications of QDs continue to expand, i.e. in vivo imaging, light-emitting devices, photodetection or solar energy conversion [1].
