Perspiration-Wicking and Luminescent On-Skin Electronics Based on Ultrastretchable Janus E-Textiles

“…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 .…”

Persistent Luminescence‐Based Theranostics for Real‐Time Monitoring and Simultaneously Launching Photodynamic Therapy of Bacterial Infections

“…[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.…”

Controlling X-ray-activated persistent luminescence for emerging applications

“…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).…”
