Abstract

Under 980 nm excitation, Eu 3 + Tm 3 + Yb 3 + tri-doped Y F 3 nanocrystals emitted ultraviolet and visible fluorescence. Besides the upconversion emissions from Tm 3 + ions, not only were the unusual D 2 5 F 3 7 , D 3 5 F J 7 emissions of Eu 3 + observed, but also the ultraviolet upconversion luminescence of Eu 3 + from H 3 7 5 , G 2 6 5 , L 6 5 F 0 7 transitions were recorded. This unique optical property was attributed to the bridging function of Tm 3 + ions in populating high-energy states of Eu 3 + ions.
