“…11 Persistent luminescence nanoparticles (PLNPs) with reproducible afterglow properties present great potential for low-background imaging in vivo . 12,13 Unfortunately, conventional single-emissive PLNPs are prone to produce inaccurate results because their luminescence intensity is susceptible to exogenous factors such as probe concentration, instrumental conditions, and time gating. 14,15 Our previous work has demonstrated that ratiometric phosphorescence sensors based on dual-emissive PLNPs can achieve self-calibrated readings and low background imaging, effectively circumventing the interference of the aforementioned exogenous factors.…”

“…Persistent luminescence nanoparticles (PLNPs) can store energy from the excitation source and then release it for afterglow emission. − Their non-in situ excitation could eliminate the interference from autofluorescence and scattered light. − If near-infrared (NIR) afterglow is realized for PLNPs, the imaging efficiency could be improved for the deep tissue penetration of NIR afterglow and the high resolution of optical imaging. − Thus, NIR afterglow for PLNPs with non-in situ excitation is perfect for imaging application. PLNPs are composited with the host, emission center, and trap, while emission centers govern the emission wavelength .…”

Near-infrared (NIR) persistent luminescence nanoparticles (PLNPs) showed great potential for bioimaging due to their integration of non-in situ excitation and deep tissue penetration. However, PLNPs are often introduced with Cr 3+ ions as the NIR emission centers. Herein, we report Cr-free Bi 2 Ga 3.985 O 9 :1.5% Fe 3+ (BGF), with Fe 3+ ions as the NIR emission centers. BGF under 310 nm excitation exhibited NIR afterglow emission at 794 nm in the first biological imaging window (650− 950 nm), with the afterglow duration of 3 h. BGF was grafted with hydroxyl groups and then polydopamine (PDA) for the integration of indocyanine green (ICG) through π−π stacking and hydrophobic interactions, as the PLNP−PDA−ICG composite. Bi in the composite, as a heavy atom element, exhibits computed tomography (CT) contrast capacity, while PDA is a photothermal agent, and ICG is excited to produce reactive oxide species for photodynamic therapy. The afterglow/CT dual-modality imaging-guided photothermal/photodynamic combination therapy was validated with in vitro/vivo imaging and therapeutic applications. This work provides the Cr-free PLNP composite for drug-free theranostics with a low toxicity.

Lanthanide‐doped scintillators have the ability to convert the absorbed X‐ray irradiation into ultraviolet (UV), visible (Vis), or near‐infrared (NIR) light. Lanthanide‐doped scintillators with excellent persistent luminescence are emerging as a new class of persistent luminescent materials recently. They have attracted great attention due to their unique "self‐luminescence" characteristic and potential applications. In this review, we comb through and focus on current developments of lanthanide‐doped persistent luminescent scintillators (PerLSs), including their persistent luminescence mechanism, synthetic methods, tuning of persistent luminescent properties (e.g. emission wavelength, intensity, and duration time), as well as their promising applications (e.g. information storage, encryption, anti‐counterfeiting, bio‐imaging, and photodynamic therapy). We hope this review will provide valuable guidance for the future development of PerLSs.
