Cathodo- and photoluminescence in Yb3+-Er3+ co-doped PbF2 nanoparticles
We have prepared and studied the PbF2:(Yb3+,Er3+) co-doped nanoparticles, with chemical formula (Yb-Er)xPb1-xF2+x, where x = 0.29, Yb3+/Er3+ = 6, and estimated the energy efficiency for their cathodoluminescence, mostly of Yb3+, and up-conversion photoluminescence of Er3+ to reach more than 0.5% and 20%, respectively, which may be the highest to date for rare-earth doped nanoparticles. Electron beam induced temperature rise in the nanoparticles has been estimated by measuring the ratio of green emission bands of Er3+. These high efficiencies are due to high doping level of nanoparticles and due to low phonon energy of the PbF2 host.

Abstract

We have prepared and studied the PbF2:(Yb3+,Er3+) co-doped nanoparticles, with chemical formula (Yb-Er)xPb1-xF2+x, where x = 0.29, Yb3+/Er3+ = 6, and estimated the energy efficiency for their cathodoluminescence, mostly of Yb3+, and up-conversion photoluminescence of Er3+ to reach more than 0.5% and 20%, respectively, which may be the highest to date for rare-earth doped nanoparticles. Electron beam induced temperature rise in the nanoparticles has been estimated by measuring the ratio of green emission bands of Er3+. These high efficiencies are due to high doping level of nanoparticles and due to low phonon energy of the PbF2 host.
