Abstract

This work shows that, counterintuitively, adding extremely small (< 10 nm in dimension) fully absorbing metal nanoparticles to a material can notably enhance its light emission. It also shows that the mystery behind the unexpected large enhancements in surface-enhanced Raman spectroscopy, even greater than a factor of 10(10), is the tunneling out of photons from the strongly absorbing metal surface. Dynamics in a strongly coupled emitter-matter quantum system demands such behavior in the case of limiting small metal nanoparticles and proximal metal surfaces. This effect can be exploited further in light generation, optical sensing, and radiative heat transfer.
