Rare-earth-ions doped into solids provide a promising system for quantum optics/information applications due to their narrow linewidths and long-lived quantum coherences. However, their emission rates are typically ultra-low. We present a fiber-based microcavity setup where the emission rate of an Europium-doped nanocrystal (Eu3+:Y2O3) can be enhanced by the Purcell effect, offering the potential for an efficient optical link to single emitters or small ensembles. As a first step, we perform room-temperature confocal microscopy of individual nanocrystals without cavity and assess their fluorescence spectra and emission lifetimes. We furthermore report on our current efforts towards observing Purcell-enhanced emission from ions coupled to a fiber-based microcavity.
