The tremendous advancement in material growth by colloidal synthetic procedures has allowed the properties of several compounds to be tailored with nanoscale precision, accelerating the development of optoelectronic devices, such as laser, LEDs and TV display technologies. At the single particle level, individual nanocrystal acts as an artificial atom, and they are capable to generate quantum light (e.g. single photons). In this lecture, we will review the main excitations in nanoscale materials, the radiative and non-radiative exciton recombination dynamics and their impact on the generation of quantum light. Examples of efficient quantum light sources will be presented, their peculiar photon statistics, with a detailed description of the experimental methods used to characterize them.
