Single photon source
A method for producing a single photon source includes functionalizing a top surface of a plasmonic thin film to form a functionalized thin film, depositing a polymer on top of the functionalized thin film, lithographically patterning the polymer to form patterned functionalized sites, and targeting nanodiamond particles to the patterned functionalized sites.
