摘要
Individual colloidal core-shell nanocrystals represent very promising single photon emitters. Recently, progress concerning the synthesis of their shell enabled strong reduction of their fluorescence intermittency, which was their main drawback. We show that the synthesis of thick shells also enables us to modify the Auger effect efficiency which is a crucial parameter to control the quantum optical properties of an individual nanocrystal fluorescence. We demonstrate that these improvements open the possibility of generating quantum cascades of photons.
