Abstract
Luminescent lanthanide nanocrystals (NCs) are proposed to be a promising newclass of fluorescent labeling agents due to their attractive optical and chemicalfeatures including low toxicity, wide photoluminescence (PL) emission and highresistance to photobleaching. In this paper, an ionic-liquid-induced synthesis ofCe1 − xTbxF3 nanoparticle was investigated via utilizing a capillary microreactor. Ionic liquid-[bmim]BF4 acts as both a fluoride source and stabilizing solvent during the reaction, which was shownto be a key factor that governs luminescence intensity of the obtained nanoparticles. Theluminescent properties can be greatly improved by optimizing the volume percentage of[bmim]BF4. Furthermore, the reaction temperature exerts an influence on the properties ofthe prepared samples. Experimental results show that the colloidal solutions ofTb3 + -dopedCeF3 NCs exhibit thecharacteristic emission of Ce3 + 5d–4f and Tb3 + 5 D4–7FJ (J = 6–3) transitionswith 5D4–7F5 green emission at 542 nm as the strongest peak. The as-prepared samples are founddispersible in water with the quantum yield (in aqueous solution) as 12%, which indicates apotential application on biolabels, light-emitting diodes (LEDs) and redox luminescentswitches.
