Abstract Cr3+/Cr4+‐activated near‐infrared (NIR) luminescent materials have attracted
extensive attention owing to their tunable emission wavelength and widespread applications …

Here, the present research situation of all inorganic thermometers based on fluorescence
intensity ratio (FIR) technology is reviewed. The thermometers are classified in detail based …

Persistent luminescence (PL) is a distinctive optical phenomenon with long‐lasting afterglow
emissions after the cessation of excitation, thus emerging huge prospects in the applications …

High‐radiance near‐infrared (NIR) phosphor‐converted light‐emitting diodes (pc‐LEDs) are
demanded for wearable biosensing devices and the properties of these pc‐LEDs are highly …

Currently, most of the mechanoluminescence (ML) phosphors strongly depend on
postirradiation stimulation using ultraviolet light (denoted as “UV exposure” from hereon) to …

The Cr 3+-activated phosphor properties are discussed in detail from an aspect of
spectroscopic point of view. The host materials considered here are a various kind of oxide …

Nowadays, materials with persistent luminescence (MPLs) have attracted growing attention
in the photocatalytic field because they can act as an inner light source to irradiate the …

Persistent luminescence nanoprobes (PLNPs) can remain luminescent after ceasing
excitation. Due to the ultra-long decay time of persistent luminescence (PersL) …

Abstract Bismuth cations (eg, Bi3+, Bi2+) are very promising non‐rare‐earth activators in
persistent luminescence (PersL) materials. Recently, much work has been devoted to …

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 …
