Abstract

Photoluminescence from metal nanostructures following intense ultrashort illumination is a fundamental aspect of light–matter interactions. Surprisingly, many of its basic characteristics are under ongoing debate. Here, we resolve many of these debates by providing a comprehensive theoretical framework that describes this phenomenon and support it by an experimental confirmation. Specifically, we ...
