In this work, we report on structural and spectroscopic properties of Yb 3+ doped and Pr
3+/Yb 3+ co-doped TeO 2-Bi 2 O 3-ZnO-Li 2 O-Nb 2 O 5 (TBZLN) tellurite glasses. Bending …

Na 0.5 Bi 0.5− x− y Yb x Pr y TiO 3 (NBT: xYb/yPr) ceramics with different Yb and Pr contents
are prepared. Both the down-conversion (DC) and up-conversion (UC) photoluminescence …

Calcium yttrium tetrametagermanates Y2CaGe4O12 doped with Er3+ and Er3+/Yb3+ reveal
upconversion emission in visible spectral range under near-infrared excitation, λex= 980nm …

Near infrared sensitized white light emitting glass has been developed and demonstrated.
The white light comes from a combination of radiations emitted from triple rare earth ions (Er …

Transparent oxyfluoride nano-glass-ceramics (GCs) containing NaGdF 4 nanocrystals
doped with 0.1 Pr 3+ and 0.5 Pr 3+, and co-doped with 0.5 Pr 3+-2Yb 3+ ions (mol%) were …
