摘要：

The ability of SrFBr nanocrystals codoped with similar to 1 mol% of Er3+ and Yb3+ to perform infrared-to-visible light upconversion is demonstrated. The average and local crystal structures conform to those expected on the basis of the P4/nmm tetragonal space-group. Excitation of Yb3+ at 980 nm results in two-photon upconversion and green-yellow luminescence from Er3+. The H-2(11/2), S-4(3/2), and F-4(9/2) excited states of the Er3+ activator in the SrFBr host exhibit a biexponential decay with lifetimes in the 100-200 and 300-400 mu s ranges.
