要旨

A WO3/Au composite thin film is prepared by depositing gold nanoparticles onto the surface of a vacuum-evaporated WO3 thin film through a spin-coating technique. It is found that the photochromism of the WO3 thin films are enhanced greatly after the modification with Au nanoparticles. The enhancement effect is explained according to the Schottky barrier formed at the WO3/Au interface and the surface effect of the gold nanoparticles. The results may be helpful in technical applications and provide a more detailed understanding of the photochromic mechanism.

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.
