Uniaxial strain tuning of organic molecule single photon sources.

Organic fluorophores are excellent single photon sources, combining high brightness, lifetime-limited linewidths and useful emission wavelengths. A key factor in their performance as photon emitters is their dynamic frequency tunability, which can be used to render the emission from multiple molecules indistinguishable. In this work we demonstrate dynamic tuning of dibenzoterrylene molecules embedded in anthracene crystals through the application of uniaxial strain fields.

Narrow and Stable Single Photon Emission from Dibenzoterrylene in para-Terphenyl Nanocrystals.

Single organic molecules are promising photon sources for quantum technologies. In this work we show photon emission from dibenzoterrylene, a widely used organic emitter, in a new host matrix, para-terphenyl. We present a reprecipitation growth method that produces para-terphenyl nanocrystals which are ideal for integration into nanophotonic devices due to their small size.
