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 …

Sol–gel processing is well-known to be a powerful technique for designing materials for
optical applications. Here, some recent applications of functionalized sol–gel coatings in …

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 …

One type of commonly used luminescent material is so-called metal-ion doped phosphor. In
such materials, optical and luminescent characteristics may be controlled by the host and …

Pure and rare earth doped gadolinium oxide (Gd2O3) waveguide films were prepared by a
simple sol–gel process and dip-coating method. Gd2O3 was successfully synthesized by …

Besides well-known quantum dots, lanthanide-doped oxide nanocrystals form a new
promising class of nanophosphors. Lanthanide vanadate and phosphate nanoparticles are …

Luminescence, energy transfer, and upconversion mechanisms of nanophosphors (Y2O3:
Eu3+, Tb3+, Y2O3: Tm3+, Y2O3: Er3+, Yb3+) both in particle and colloidal forms were …

Atomic layer deposited (ALD) Y2O3 thin films have been thoroughly investigated for optical
or electronic applications. The coherent spectroscopy of lanthanide ions doped into this …

Vanadium dioxide is a well-known near room temperature phase transition material with a
transition temperature (τ C) at 68° C. In this paper, Eu3+ dopant with different doping levels …

Pure and rare earth ions doped yttrium oxide (Y2O3) waveguide films were prepared by a
simple sol–gel process and dip-coating technique. Y2O3 were successfully synthesized by …
