DOI: 10.1002/adom.202501654

Abstract: Underwater imaging (UI) technology is of considerable importance in scientific, economic, and societal contexts. The utilization of underwater near‐infrared (NIR) single‐pixel imaging (SPI) has been posited as a potentially viable alternative to conventional imaging systems.… read more here.

DOI: 10.1021/acs.nanolett.4c03187

Abstract: Advanced photodetectors are crucial for high-fidelity optical communication. However, the tradeoff between high external quantum efficiency (EQE) and high light fidelity (Li-Fi) frequency often limits data transmission accuracy and timeliness. Here, we report a photodetector… read more here.

DOI: 10.1021/jacs.4c00402

Abstract: The optoelectronic properties of colloidal quantum dots (cQDs) depend critically on the absolute energy of the conduction and valence band edges. It is well known these band-edge energies are sensitive to the ligands on the… read more here.
