Breaking the diffraction limit in absorption spectroscopy using upconverting nanoparticles
We employ a single optically trapped upconverting nanoparticle (UCNP) of NaYF(4):Yb,Er of diameter about 100 nm as a subdiffractive source to perform absorption spectroscopy. The experimentally expected mode volume of 100 nm of the backscatter profile of the nanoparticle matches well with a numerica...
