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 …

Persistent luminescence nanoparticles (PLNPs) are a kind of phosphors that can remain
luminescent for seconds to several days after the stoppage of excitation. Lanthanides show …

When the bright green-emitting SrAl 2 O 4: Eu, Dy persistent phosphor was described in the
literature in 1996, this presented a real breakthrough in performance, both in terms of initial …

Photochromism is an interesting approach to improve the anticounterfeiting of various
commercial commodities. To introduce a transparent anticounterfeiting nanocomposite, it …

Making a further insight into the structure-property relation of luminescent materials is not
only in theory but also with reference value in developing more practical materials in this …

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

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 …

We investigate native point defects and rare-earth (co) dopants in monoclinic Sr Al 2 O 4
using hybrid density-functional defect calculations. Europium (Eu) and dysprosium (Dy) are …

Despite significant interest in persistent luminescence materials, the focus of all recent works
remains on the exploitation of materials in powder form. Here, a new point of view based on …

Abstract SrAl 2 O 4: Eu, Dy is a representative persistent luminescent phosphor that has
been widely investigated. However, the mechanism of its long-lasting action has not been …
