Lanthanides-based nanomaterials have a plethora of potential applications for luminescent bioassays and bioimaging technologies. Europium(III) metal ions are of interest in luminescent bioassays because of their long luminescent lifetime and large Stocks shifts. Our research is focused on developing novel synthetic methods to prepare highly monodispersed nanoparticles with enhanced luminescent properties. Here, we report the synthesis of Eu(III) metal-doped calcium fluoride nanoparticles using a water-based microwave synthetic method. With significant shorter synthesis times and a more uniform heating gradient, we have been able to consistently produce Eu(III)-doped calcium fluoride nanoparticles with their sizes ranging from 60 to 350 nm. We hypothesized that the nanoparticles with smaller sizes exhibit higher luminescent efficiencies compared to those with relatively larger sizes due to the energy transfer mechanism. A comparison of the luminescent quantum yields to the particle sizes will be presented.
