Enhanced cooperative near-infrared quantum cutting in Pr3＋- Yb3＋ co-doped phosphate glass

Pr3＋ and Yb3＋ co-doped phosphate glasses are prepared to study their optical properties. Excitation and emission spectra and decay curves are used to characterize their luminescence. We demonstrate that upon excitation of Pr3＋ ion with one high energy photon at 470 nm, two near-infrared （NIR） photon...

More Information
Summary:Pr3＋ and Yb3＋ co-doped phosphate glasses are prepared to study their optical properties. Excitation and emission spectra and decay curves are used to characterize their luminescence. We demonstrate that upon excitation of Pr3＋ ion with one high energy photon at 470 nm, two near-infrared （NIR） photons are emitted at 950-1100 nm （yb3＋：2F5/2 - 2F7/2） through an efficient cooperative energy transfer （CET） from Pr3＋ to Yb3＋. The maximum energy transfer efficiency （ETE） and the corresponding quantum efficiency approach up to 90.17% and 190.17%, respectively. The glass materials might find potential application for improving the efficiency of silicon-based solar cells.
