Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Advanced Functional Materials, EarlyView.A two‐step DNA metallization process is presented for the modular assembly of metal sulfide nanoparticles (NPs) on MoS2, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs. This allowed to tailor the photoinduced electrical response of phototransistors to different wavelengths, according to the ...

Advanced Functional Materials, EarlyView.Triple Passivation Treatment (TPT) strategy enables 1.75 eV wide‐bandgap perovskite solar cells (WB‐PSCs) with suppressed halide phase segregation and n‐to‐p type surface transition. The photoluminescence quantum yield increases from 0.5 to 2.1%, indicating reduced non‐radiative losses.
