Transparent oxyfluoride nano-glass-ceramics have been prepared by melting-quenching
and doped with five different Nd 3+ concentrations (0.1–2 mol%) to obtain the most efficient …

The zirconia samples containing two different concentrations of Er and Yb dopants were
prepared using the Sol–Gel method and up-conversion luminescence was studied using the …

Complex fluorides, especially rare-earth doped NaREF 4 (RE= Y 3+, La 3+ or Gd 3+), are
promising materials for the upconversion luminescence mostly due to low phonon energy of …

Abstract Er 3+/Yb 3+ co-doped transparent glass ceramics containing Na 3.6 Y 1.8 (PO 4) 3
crystals were prepared by high-temperature melting and subsequent heat treatment the …

In the course of this research several NaLaF 4 samples doped with different Er 3+ and Nd 3+
concentrations have been synthesized. For these samples photoluminescence spectra …
