“…For the aforementioned reasons, a power supply driven by sustainable, safe, and biocompatible energy sources is commanding. Mechanoluminescence (ML), a form of light emission, happens when stress-sensing materials convert mechanical energy into photons. , The brightness of ML strongly depends on the applied force, and it can be generated through various mechanisms, including fracto-, piezo-, and triboluminescence. − In recent years, great efforts have been made to develop various ML materials, such as quaternary oxysulfides, oxonitridosilicates, niobates, and stannates . Due to its interesting properties, ML has been widely applied in lighting, displays, stress sensing, photonic skin, and optogenetics. − Importantly, ML employed as a self-powering system totally works in a sustained way, which is highly significant for the development of internal light sources.…”

External light sources, such as lasers, light emitting diodes (LEDs) and lamps, are widely applied in photodynamic therapy (PDT); however, their use is severely limited by the nature of shallow tissue penetration depth. The recent exploration of light delivery or local generation on tumor sites has attracted much attention, owing to the fact that these systems are significantly endowed with high tissue penetration. In this review, we briefly introduced the principle of "onspot light generation or delivery systems" in PDT. These systems are divided into different categories: (1) implantable luminescence, (2) mechanoluminescence, (3) electrochemiluminescence, (4) Cerenkov luminescence, (5) chemiluminescence, and (6) bioluminescence. Finally, their applications, advantages, and disadvantages in PDT will be appropriately summarized and further discussed in detail. We believe that this review will provide general guidance for the further design of light generation or delivery systems and clinical studies for PDT-mediated cancer treatments with unparalleled merits.

With the progress of forgery and decryption, the traditional encryption technology is apparent not enough, which strongly requires the development of advanced multidimensional encryption strategies and technologies. Photo-stimuli responsive fluorescent materials are promising as candidate materials for advanced information encryption. Here, we have reported new photo-stimuli responsive materials by encapsulating photochromic molecules spiropyrans (SPs) into naphthalimide-functionalized silica aerogels. By introducing different modification groups (dimethylamino) into 1,8-naphthalimide, we obtained two kinds of silica aerogels that emit blue and green colors. The naphthalimide-functionalized silica aerogels/dye composite exhibits a blue (dimethylamino-modified naphthalimide-functionalized silica aerogel showing green) emission from naphthalimide of silica aerogels at 450 nm (520 nm) and a red emission around 650 nm of SP. Under exposure to ultraviolet light, SP gradually transformed into the merocyanine (MC) form, and a strong absorption band appeared near 540 nm. At that time, the fluorescence resonance energy-transfer (FRET) process occurred between naphthalimide and the MC isomer. As the irradiation time is extended, the fluorescence color changes continuously from blue (green) to red through the FRET process. Using the time dependence of fluorescence, dynamic encryption patterns and multiple codes were successfully developed based on these functionalized silica aerogels. This work has provided important guidance for designing advanced information encryption materials.

“…Nevertheless, the ML emission characteristics and colors are highly dependent on the dopant ions, resulting in the dual-modal sensing properties of ML materials being typically limited to specific ions or combinations of ions with different ML responses in the same matrix, discouraging the flexibility in the design of dual-modal sensors. Currently, composites that combine multiple materials within a single system have shown excellent performance stress and temperature sensing as them could flexibly combine the luminescent properties of each component to achieve the desired performance. − Therefore, the utilization of composite materials with stress and temperature responses holds great promise for the efficient development of visualized dual-modal sensors.…”

The visualized dual-modal stress-temperature sensing refers to the ability of a sensor to provide real-time and visible information about both stress and temperature and has indeed attracted significant interest in various fields. However, the development of convenient methods for achieving this capability remains a challenge. In this work, a dual-modal stress-temperature sensor is successfully fabricated using a ZnS/Cu@CsPbBr1.2I1.8 glass ceramics (GCs)/polydimethylsiloxane (PDMS) (ZCP) composite film. The tunable ML color is achieved by modulating the concentration of CsPbBr1.2I1.8 GCs in the ZCP composite films based on the light conversion process from ZnS/Cu to CsPbBr1.2I1.8 GCs. Additionally, the stress and temperature can be visualized simultaneously by integrating the ML intensity and ML color of the ZCP composite film. This feature allows for the real-time monitoring of automotive tire temperature by embedding the ZCP composite film on the tire surface, enabling a strong and stable response to both stress and temperature changes. Overall, this work offers a convenient, efficient, and repeatable approach for achieving visualized dual-modal stress-temperature sensing in the fields of mechanical engineering, structural health monitoring, and intelligent devices.
