Fluorescence excitation of impurities doping crystals and polymers using single molecule spectroscopy

Abstract

Single molecule spectroscopy is now a well known technique and a lot of new fields of research begun recently. In this paper we present results we obtained in p-terphenyl crystals where we conbined our technique with detection of magnetic resonance. In polyethylene matrix we obtained with Rhodamine 640 interesting results which we compare with our results on the same system using hole burning.
