Abstract Skin‐like thermoelectric (TE) films with temperature‐ and strain‐sensing functions are highly desirable for human‐machine interaction systems wearable devices. However, current TE still face challenges in achieving high flexibility excellent sensing performance simultaneously. Herein, the first time, a facile roll‐to‐roll strategy is proposed to fabricate an ultraflexible chalcogenide glass‐polytetrafluoroethylene composite film superior performance. The unique reticular network of...
Fiber-based inorganic thermoelectric (TE) devices, owing to the small size, light-weight, flexibility, and high TE performance, are promising for applications in flexible thermoelectrics. Unfortunately, current fibers strictly constrained by limited mechanical freedom because of undesirable tensile strain, typically a value 1.5%, posing strong obstacle further application large-scale wearable systems. Here, superflexible Ag
As a new member of laser glass family, bismuth‐doped glasses have received rising interests due to the application fiber amplifiers and sources in spectral range for next‐generation optical communication system. For practical glasses, it must be considered on how improve luminescence efficiency. Here, we demonstrate that addition aluminum can enhance bismuth near‐infrared by more than 10 000 times, which is right followed discussion mechanism why this happen. We believe work helpful...

For phosphor‐converted warm white light‐emitting diodes ( WLED s), it is essential to find highly efficient red oxide phosphors, which are better chemically stable and benign environment can be prepared in a much milder condition.

Best performance the reached when synthesized mild reaction condition, that is, at 850°C for 3 h...
Broadband near-infrared (NIR)-emitting materials are crucial components of the next generation smart NIR light sources based on blue light-emitting diodes (LEDs).
