Introduction to Quantum dots

Quantum dots (QD) are an exciting new area of research; they have valuable properties that could further the future of opto-electronic devices. Such properties can be probed by performing photo-luminescence (PL) experiments, which is essentially excitation of the dots by optical means and detecting the photo-luminescence emitted. Using this technique, the temperature and excitation intensity dependence of the PL from four different quantum dots have been investigated.
