摘要：

In present study, we report on synthesis of fluorescent GdVO4:Eu3+ nanoparticle-embedded CaCO3 microparticles (CaCO3 @ GdVO4:Eu3+) and their characterization. Synthesized CaCO3@GdVO4:Eu3+ microspheres are of vaterite polymorph and about 2μm diameter with -12.80±0.82 mV zeta potential. The specific surface area of the CaCO3@GdVO4:Eu3+ microspheres and pore size distribution were analyzed by Brunauer-Emmett-Teller method. The microparticles was classified as macroporous ones with a wide distribution of pore sizes. The specific surface area for CaCO3 @ GdVO4:Eu3+ microspheres (SBET = 25.2 m2/g) is higher than reported for CaCO3 microparticles obtained without any additives. CaCO3 @ GdVO4:Eu3+ microspheres exhibit strong fluorescence both in a water solution and under fluorescent microscopy conditions that makes them attractive for bio-related application. © 2017-STC Institute for Single Crystals"."
