Photodetectors
The cover image describes the design of three‐electrode photo‐electrochemical photodetectors based on lanthanide‐doped carbon quantum dots (CQDs). Owing to the coordination of lanthanides and internal energy transfer between lanthanides and CQDs, the as‐fabricated photodetectors not only show an excellent photo‐response performance, but also exhibit a narrow‐band response behavior....
The present work demonstrates a facile hydrothermal approach to synthesize lanthanide‐doped carbon quantum dots (CQDs) with europium and/or gadolinium elements. Taking the advantage of broadband adsorption in the ultraviolet‐visible region, the doped QDs are directly used as building blocks for photo‐electrochemical (PEC)‐type photodetectors (PDs) and their performance is systematically investigated...
