Redox-active triphenylamine-appended pyrazinacenes show extreme reversible redox-coupled switching of their photophysical properties. In their reduced state, absorption and emission bands fall well ...

It is based on a high-precision, short-wave infrared imaging method that can record rare-earth doped nanoparticle photoluminescence lifetimes in the micro-to millisecond range. Jinyang Liang, INRS ...

Peking University, December 3rd, 2024: Prof Zhang Zhiyong’s team developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...

Researchers have improved upon techniques that use thin films to compress infrared light, demonstrating three advantages that make the films more useful for practical applications. The researchers ...

A layered graphene and chromium oxychloride device functions as a broadband optical synapse, detecting visible to deep infrared light and learning image orientation through built-in memory. (Nanowerk ...
