title: Multiphoton near-infrared quantum cutting luminescence of Yb3+ ion cooperative energy transferred from the oxyfluoride vitroceramics phosphor matrix.
abstract: In this Letter, we reported on an interesting multiphoton infrared quantum cutting phenomenon in Yb(3+)Tb3(+)-doped oxyfluoride vitroceramics phosphors. From the study results it is found that the absorption of one 288.0 nm photon of the matrix results in the emission of two 975.5 nm photons of the Yb3+ ion. In addition, it is found also that one 255.0 nm photon of the matrix may result in the emission of three 975.5 nm photons of the Yb3+ ion, due to the fact that their cooperative energy transfer rate is larger than multiphonon nonradiative relaxation rate.
