“…Nevertheless, the development of the mechano-/electro-induced luminescent devices ineluctably implicates complicated preparation processes, high cost, and an external power supply (e.g., electroluminescent devices require voltage higher than 1 kV) . On the other side, long persistent luminescence (LPL) materials were considered as promising alternatives in the development of visualized electronics owing to their superior luminescence properties including efficient excitations and hours-long highly visible afterglow . Upon exposure to ultraviolet or visible light, LPL materials absorb the excitation energy and release the energy very slowly (over 10 h) as colored light .…”

Stretchable electronics have attracted surging attention for next-generation smart wearables, yet traditional flexible devices fabricated on hermetical elastic substrates cannot satisfy lengthy wearing comfort and signal stability due to their poor moisture and air permeability. Herein, perspiration-wicking and luminescent on-skin electrodes are fabricated on superelastic nonwoven textiles with a Janus configuration. Through the electrospin-assisted face-to-face assembly of all-SEBS microfibers with differentiated diameters and composition, porosity and wettability asymmetry are constructed across the textile, endowing it with antigravity water transport capability for continuous sweat release. Also, the phosphor particles evenly encapsulated in the elastic fibers empower the Janus textile with stable light-emitting capability under extreme stretching in a dark environment. Additionally, the precise printing of highly conductive liquid metal (LM) circuits onto the matrix not only equips the electronic textile with broad detectability for various biophysical and electrophysiological signals but also enables successful implementation of human–machine interface (HMIs) to control a mechanical claw.

“…[14] Second, the PL emission of mPL NPs could effectively avoid the continuous use of external irradiations and alleviate autofluorescence interference from the tissues, performing much higher signal-to-noise ratios than traditional optical probes such as quantum dots and dyes. [42] Last but not least, the afterglow emission is used as an internal light source to persistently excite photosensitizers and generate ROS, which could overcome the short half-life and durability of traditional PDT. [15] ZGC NDs could be activated by LED (300-600 nm), making mPL@Pc-Cy NPs no longer limited by the afterglow time.…”

External light irradiation is usually required in bacterial infection theranostics; however, it is always accompanied by limited light penetration, imaging interference, and incomplete bacterial destruction. Herein, a feasible “image‐launching therapy” strategy is developed to integrate real‐time optical imaging and simultaneous photodynamic therapy (PDT) of bacterial infections into persistent luminescence (PL) nanoparticles (NPs). Mesoporous silica NPs are used as a substrate for in situ deposition of PL nanodots of ZnGa2O4:Cr3+ to obtain mPL NPs, followed by surface grafting with silicon phthalocyanine (Si‐Pc) and electrostatic assembly of cyanine 7 (Cy7) to fabricate mPL@Pc‐Cy NPs. The PL emission of light‐activated mPL@Pc‐Cy NPs is quenched by Cy7 assembly at physiological conditions through the fluorescence resonance energy transfer effect, but is rapidly restored after disassembly of Cy7 in response to bacterial infections. The self‐illuminating capabilities of NPs avoid tissue autofluorescence under external light irradiation and achieve real‐time colorimetric imaging of bacterial infections. In addition, the afterglow of mPL NPs can persistently excite Si‐Pc photosensitizers to promote PDT efficacy for bacterial elimination and accelerate wound full recovery with normal histologic features. Thus, this study expands the theranostic strategy for precise imaging and simultaneous non‐antibiotic treatment of bacterial infections without causing side effects to normal tissues.

“…Consequently, the research of X-PersL had received minimal attention and made very little progress in the following years. The revival of X-PersL research in the 2010s was largely motivated by the difficulty of pushing traditional UV-charged PersL materials that emit in a relatively narrow wavelength range with limited brightness [2,15,35]. By leveraging X-ray excitation, highly tunable PersL across the full spectrum has been realized in various lanthanide and transition-metal ions, enabling diverse applications such as biomedical theranostics, information storage, and flexible-panel X-ray imaging (Figure 1).…”
