In this paper, we demonstrate multifunctional upconversion nanoparticles with intense near-infrared emission and unique magnetic properties for dual-modal upconversion luminescent bioimaging and T2-weighted magnetic resonance imaging. High-quality BaYbF5:Tm3+ nanoparticles are synthesized via a hydrophobic method and then converted to be hydrophilic via a hydrochloric acid treatment. The as-synthesized nanoparticles are cubic phase and about 6 nm in diameter with narrow size distribution. The intense near-infrared emission makes these nanoparticles can be acted as bio-probes in upconversion luminescent bioimaging with deep tissue penetration. Besides, these nanoparticles can also be used as T2-weighted contrast agents in magnetic resonance imaging due to the high value of relaxation rate (r2 = 4.05) in 0.55 T. This finding may have further bio-applications in the future due to the high performance of these BaYbF5:Tm3+ nanoparticles in dual-modal bioimaging.
