Operable persistent photoconductivity of Bi2S3 nested nano-networks
文献信息

Recently, hierarchical nanostructures have attracted increasing attention because of their large specific surface area and abundant physical characteristics. Here we propose a hierarchical Bi2S3 nested nano-network (Bi2S3-3N) with an excellent thermally-stable lattice structure, which is prepared by topotactic transformation. Experimental results revealed that for the first time, Bi2S3-3N possesses an interesting nature of the repetitively-operable persistent photoconductivity, which is believed to stem from the releasing of photo-stimulated carriers captured by deep-level traps. This work shows great potential of topotactic transformed Bi2S3 hierarchical nanostructures in practical applications like functional porous nanoarchitectures, bistable optical-switching, photo detectors, memory, etc.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
