Abstract

Gold nanoparticles emit broad-band upconverted luminescence upon irradiation with pulsed infrared laser radiation. Although the phenomenon is widely observed, considerable disagreement still exists concerning the underlying physics, most notably over the applicability of concepts, such as multiphoton absorption, inelastic scattering, and interband vs intraband electronic transitions. Here, we ...
