Abstract: The quantum cutting phenomenon of a blue photon into two infrared photons is reported in glass codoped with Pr3+-Yb3+ ions. Oxyfluoride glass with compositions of 32SrF2-0.1PrF3-2.9YbF3-42SiO2-23Al2O3 were prepared, and photoluminescence properties in the range from visible to near-infrared were investigated. Evidence of several energy transfers, such as (Pr3+:3P01G4)→(Yb3+:2F5/22F7/2) and (Pr3+:1D23F4, 3F3)→(Yb3+:2F5/22F7/2), were demonstrated in the Pr3+-Yb3+ co-doped glass. By comparing excitation spectrum of the Yb3+ emission with absorption spectrum of Pr3+, we obtain direct evidence of quantum cutting by excitation to Pr3+:3PJ levels at 420 ~ 490 nm.
