Great progress has been made in inorganic persistent phosphors, especially in the recent
two decades, motivated by the discoveries of the SrAl 2 O 4: Eu 2+-Dy 3+ in the green and …

The development of probes for biomolecular imaging and diagnostics is a very active
research area. Among the different imaging modalities, optics emerged since it is a …

Mechanoluminescent materials, which emit light in response to mechanical stimuli, have
recently been explored as promising candidates for photonic skins, remote optogenetics …

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 …

Long persistent phosphors (LPPs) can maintain luminescence for an appreciable time after
terminating the excitation light, which can be compared to an optical battery. This intriguing …

Persistent luminescence (PersL) materials that can be excited by natural sunlight are in
great demand to reduce energy consumption, but the design and development of efficient …

Many in vivo biological techniques, such as fluorescence imaging, photodynamic therapy,
and optogenetics, require light delivery into biological tissues. The limited tissue penetration …

This essay draws attention to lanthanide luminescence by putting into perspective the
sensitization process of f–f emission, the design of highly luminescent lanthanide‐based …

Lanthanide luminescence is at the heart of applications as diverse as lighting,
telecommunications, lasers, security marking, barcoding, luminescent molecular …
