Abstract:
Water-soluble and amino-functionalized luminescent Dy3+-doped BaFCl nanocrystals have been synthesized for the first time via a facile one-step modified solvothermal method with polyethyleneimine (PEI) as capping agent. The obtained BaFCl:Dy3+ nanocrystals have a size of about 40 nm, remain stable in aqueous solutions under different pH, and exhibit intense visible luminescence of Dy3+. The synthesized nanocrystals featuring long-lived luminescence may have potential applications as time-resolved photoluminescent probes for bio-applications.
