Coinage metal nanoparticle emission : Near‐infrared photoluminescence is observed for small‐diameter (≈2–3 nm) copper and silver nanoparticles upon UV‐vis excitation. Periodic trends are studied and reveal remarkably similar quantum yields, observed lifetimes, excitation pathways, and emission‐peak features upon comparison to each other as well as to previously reported small‐diameter gold nanoparticles (AuNPs), indicating that these processes may be universal across the coinage metals. The new particles and their emission properties are intriguing cost‐effective alternatives to AuNPs in near‐infrared‐based applications such as biological imaging and sensing.
