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

Embodiments relate to a quantum rod, a quantum rod film, a quantum rod display device with a quantum rod. The quantum rod includes a first core, a second core separated from the first core, and a first shell surrounding the first and second cores.

A method of producing electronic plasmons by applying a bias to a molecular tunnel junction to excite plasmons, in which the molecular tunnel junction contains a top metallic electrode formed of a eutectic metal alloy and a metal oxide, a bottom metallic electrode formed of a transition metal, and a self-assembled monolayer formed of a plurality of organic molecules disposed between the top metallic electrode and the bottom metallic electrode. Also disclosed are a molecular tunnel junction for producing electronic plasmons and a method for preparing such a molecular tunnel junction.

The invention related to single photon emission systems based on nano-diamonds. Single-photon sources have a broad range of applications in quantum communication, quantum computing and quantum metrology.
