Glow‐in‐the‐dark materials have been around for a long time. While formerly materials had
to be mixed with radioactive elements to achieve a sufficiently long and bright afterglow …

Ever since the discovery of SrAl2O4: Eu, Dy persistent afterglow material, that can
intensively glow up to 20 h, the mechanism of long-lasting luminescence has been a …

A novel Mn 4+ activated Ca 2 LaSbO 6 (CLS) far-red phosphor was synthesized by high
temperature solid state reaction. The samples were characterized by X-ray diffraction (XRD) …

It has always been a spectroscopist's dream to correlate a material's luminescence
properties with its microscopic structure, based on reliable structure–property relationships …

Lanthanide-activated alkaline earth aluminate phosphors are excellent luminescent
materials that are designed to overcome the limitations of conventional sulfide-based …

The extraordinary long phosphorescence of SrAl2O4: Eu2+: Dy3+ has been widely studied
in powder samples because of its broad range of applications in this form and despite the …

With the rapid development of the panel display market, demand for efficient light emitters as
active layers in electroluminescence (EL) devices has significantly increased. Luminescent …

Light sensors are widely used to monitor light intensities, for instance in medical
applications, in agriculture or for conservation of art. Most of these sensors are electronic …

The quantum efficiency is a key metric in lighting technology and for the quantification of
luminescent processes, indicating how many photons are emitted with respect to the number …

This book describes in detail the main concepts of theoretical spectroscopy of transition
metal and rare-earth ions. It shows how the energy levels of different electron configurations …
