Near-infrared (NIR) luminescent materials have emerged as a growing field of interest,
particularly for imaging and optics applications in biology, chemistry, and physics. However …

Abstract Er 3+/Yb 3+ co-doped large-mode-area double-cladding fibers based on Bi 2 O 3-
GeO 2-Ga 2 O 3–Na 2 O–CeO 2 glass material were fabricated using a rod-in-tube method …

Several optical applications demand for enhanced optical response of rare earth containing
glasses. In the present investigation, modification in spectral features with the dispersion of …

Ytterbium (Yb)-doped fibers using aluminophosphosilicate (Yb-APS) host glass offer
significant advantages over conventional aluminosilicate (Yb-AS) fibers, such as strong …

Previous works have been already reported on multiphonon-assisted non-resonant energy
transfer in Ce 3+-Er 3+-doped tellurite glasses. However, it is not clear the mechanism of the …

Fluoroindate glasses co-doped with Pr3+/Er3+ ions were synthesized and their near-
infrared luminescence properties have been examined under selective excitation …

The influence of temperature on the near-infrared emission band corresponding to the
radiative relaxation from 4 I 13/2 to 4 I 15/2 electronic states of Er 3+ was investigated in Y 2 …

An ultrabroadband near-infrared (NIR) emission of Ni2+ is demonstrated in a highly
transparent nanoglass ceramic (nano-GC) containing Ga2O3 nanocrystals with an 808 nm …

In this work we report on YVO 4 nanocrystalline powders doped with individual ions Nd 3+,
Er 3+ and Tm 3+, and their combination. Modified Pechini method allowed obtaining weakly …
