Abstract
The ability of SrFBr nanocrystals codoped with ∼1 mol% of Er3+ and Yb3+ to perform infrared-to-visible light upconversion is demonstrated. Excitation of Yb3+ at 980 nm results in two-photon upconversion and green-yellow luminescence from Er3+, highlighting the potential of alkaline-earth fluorohalides as hosts for Yb3+–Er3+ sensitizer–activator pairs.
