Spectroscopy and rational chemical design of single emitters for quantum photonics
Single optical emitters have developed from study objects of fundamental photophysics and local chemical dynamics to technologically relevant building blocks in optical quantum information processing (QIP). This thesis mirrors this development by bridging classical photo-physical studies of single …
