This chapter addresses the development of inorganic phosphor materials capable of
converting the near UV or blue radiation emitted by a light emitting diode to visible radiation …

Lasers based on erbium ions using 4 I 11/2​→​ 4 I 13/2 transition can generate laser
radiation in the spectral range from 2.7​ μm to 3​ μm. Since the strong absorption peak of …

The temperature determination using luminescent materials is nowadays considered the
perspective remote technique for temperature gauging, despite the few examples reported …

Abstract Near-infrared (NIR) light-emitting materials are crucial for night vision, in vivo-
imaging, and secret codes. However, issues such as thermal quenching and chemical …

Abstract Erbium-doped TiO 2 nanotubes (Er–TiO 2 NTs) are prepared with a combination of
anodization and electrochemical deposition using various proportions of erbium and …

The energy levels of Ln3+ ions are known to be only slightly dependent on the ion
environment. This allows one to predict the spectra of f–f transitions in Ln3+ complexes …

Upconversion luminescence is a nonlinear optical process achieved by certain engineered
materials, which allows conversion of low energy photons into higher energy photons. Of …

Yttrium aluminum garnet nanoparticles both undoped and doped with lanthanide ions
(Ce3+, Eu3+, Dy3+ and Tb3+) having average size around 30 (±3nm) nm were prepared by …

An investigation on the mechanical and thermal properties of Yb 3 Al 5 O 12 is conducted by
a combination of first-principles calculations and chemical bond theory calculation. Density …

Yttrium aluminum garnet Y3Al5O12 (YAG): Er3+, Tm3+ phosphor powders with preferable
luminescent properties and nanocrystals with better morphology were synthesized by the …
