(NAMI), Science Park, Hong Kong 10.3762/bjnano.9.100 Abstract Fluorescence properties of crystallographic point defects within different morphologies of titanium dioxide were investigated. For the first time, room-temperature single-photon emission in titanium dioxide opticaldefects was discovered in
-photon source within a wide bandgap semiconductor.
Keywords: fluorescence; opticaldefects; room temperature; single-photon emitters; titanium dioxide; Introduction
Single-photon sources offer non-classical states of light [1] and are a prerequisite for future quantum technologies [2]. There are many
