We report ultrasensitive sub-10 nm NaMnF3 nanocrystals codoped with Yb3+, Er3+/Tm3+ ions, and their intense pure red and near-infrared upconversion emissions in the presence of Mn2+. The nanocrystals showed excellent T1 contrast in 7 T MRI, implying their potential as single-phase contrast agents fo...
