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 …

The use of luminescence in biological systems allows us to diagnose diseases and
understand cellular processes. Persistent luminescent materials have emerged as an …

Reversible charge transfer between lanthanide ions is identified as storage mechanism for
the current workhorse persistent phosphors. Present evidence relies on sophisticated X‐ray …

We present a systematic decay analysis of four sulfide phosphors, namely SrS: Eu 2+, CaAl
2 S 4: Eu 2+, KGaS 2: Eu 2+, and NaBaAlS 3: Eu 2+. In SrS and NaBaAlS 3, there is only …

Long persistent luminescence (LPL) hosts are important and necessary, but they and their
trap mechanism have not been researched enough. Moreover, the traditional high …

The series of Gd3–x Ce x Ga3Al2O12 nanopowders doped with different concentrations of
Ce3+ ions were prepared by Pechini (sol–gel) and combustion methods. The structure and …

Abstract Green-emitting ZnGa 2 O 4: Mn 2+ persistent luminescent nanoparticles were
synthesized via a solvothermal method followed by a microwave-assisted sintering at 1150° …

Red long afterglow phosphors have significant implications for the realization of multicolor
long-afterglow phosphors, but their insufficient luminescence intensity and afterglow …

Functional materials with stable and adjustable luminescence have recently become a
research hotspot for their broad application prospects. Tunable luminescence can be …

Luminescent inorganic materials are used in several technological applications such as light-
emitting displays, white LEDs for illumination, bioimaging, and photodynamic therapy …
