Broadband Negative Photoconductive Response in Carbon Nanodots

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(32)

Published: June 10, 2024

Abstract Due to the broadband response and low selectivity of external light, negative photoconductivity (NPC) effect holds great potential applications in photoelectric devices. Herein, different photoresponsive carbon nanodots (CDs) are prepared from diverse precursors NPC CDs utilized achieve optoelectronic logic gates optical imaging for first time. In detail, mcu ‐CDs which by microwave‐assisted polymerization citric acid urea possess large specific surface area abundant hydrophilic groups as sites adsorption H 2 O molecules thereby present a high conductivity dark. Meanwhile, affinity permits light‐induced desorption heat thus endow with under illumination. The easy absorption contribute extraordinary ‐CDs.
