Author Affiliations +
In this paper we report optical hole-burning in nano- particles of MgS doped with Eu. Nano-particles have been produced by quench condensing the laser-ablated vapors from a solid target. Particle size has been controlled by the pressure of the ambient gas in the chamber. Our experiments produced particles as small as 20 nano-meters in size. Optical data shows typical fluorescence enhancement associated with the confined geometries. Results have been presented on optical properties, the hole-burning characteristics, and the broadening of holes at elevated temperatures.
