Abstract
An optical upconverting nanomaterial includes a nanocrystal, a ligand layer directly bonded to the nanocrystal, and an optical antenna directly or indirectly bonded to the nanocrystal. The nanocrystal includes a transition metal-doped material exhibiting upconversion to optical wavelengths. The transition metal-doped material includes energy transfer facilitating transition metal dopants and (not necessarily distinct) emitter transition metal dopants, where an absorption spectrum of the energy transfer facilitating transition metal dopants overlaps with an emission spectrum of the optical antenna. The optical upconverting nanomaterial has at least one linear dimension (e.g., width or thickness) that is less than 150 nm in extent.
