Since the invention and further development of lasers in the 1960s, photonics has grown
into a field that permeates virtually every aspect of modern life. As photonics deals with the …

Erbium‐doped fiber devices have been extraordinarily successful due to their broad optical
gain around 1.5–1.6 µm. Er‐doped fiber amplifiers enable efficient, stable amplification of …

The synthesis and characterization of various rare-earth (RE)-doped and codoped yttrium
oxide (Y 2O 3) nanomaterials were undertaken in the current work. RE dopants such as …

Etching of amorphous Al 2 O 3 and polycrystalline Y 2 O 3 films has been investigated using
an inductively coupled reactive ion etch system. The etch behaviour has been studied by …

High-quality reflective screens constitute an important part of multi-layer insulation materials.
However, the metal foils currently used as thermal reflective screens are easily oxidized in …

Erbium-doped yttrium oxide nanotubes (Er3+: Y2O3 NTs) with 0− 100% doping levels were
synthesized by a hydrothermal procedure followed by a dehydration process from Er3+: Y …

Rare earth (RE) doped yttria sesquioxide has been widely used as host materials for
upconversion (UC) phosphors due to their high refractive index, wide band gap, and high …

Y2O3: Er3+ films were prepared by a simple sol-gel process. The structural properties of
Y2O3: Er3+ films were characterized with X-ray diffraction, Fourier transform infrared …

Lanthanide ion-based luminescent nanomaterials have been developed for their unique
properties (ie long lifetime, narrow full width at half maximum for emission peaks, and large …

Lead antimonate glasses doped with 1.0 mol% of Er 2 O 3 and co-doped with Y 2 O 3, Sc 2
O 3 and HfO 2 were synthesized. Optical absorption and luminescence spectra of the …
