Abstract

Atom-precise copper nanoclusters (Cu NCs) with near-infrared (NIR) luminescence show promise in biomedical and optoelectronic applications, due to their cost-effectiveness, low toxicity, and tunable photophysics. However, their practical application is limited by extremely low NIR photoluminescence quantum yields (PLQYs) (
