Abstract

image

Tetsu Tatsuma and co-workers visualize in article 1400066 photoinduced charge distributions for Au nanoparticles deposited on single crystalline TiO2. The cover illustrates plasmonic gold nanoprisms on titanium dioxide substrates. The front one is irradiated with near infrared light, so that electrons are injected from the excited gold into titanium dioxide, whereas the back one is irradiated with UV light, so that electrons are transferred from excited titanium dioxide to gold.
