Abstract/OtherAbstract:
|
Room temperature single-photon emission and quantum characterization is reported for isolated defects in zinc oxide. The defects are observed in thin films of both in-house synthesized and commercial zinc oxide nanoparticles. Emission spectra in the red and infrared, second order photon correlation functions, lifetime measurements and photon count rates are presented. Both two-state and three-state emitters are identified. Sub-bandgap absorption and red emission suggests these defects are the zinc-vacancy. These results identify a new source of single-photons in a readily available wide band gap semiconductor material which has exceptional electrical, optical and biocompatibility properties. |
