Abstract
The present disclosure relates to luminescent including photon up-conversion nanoparticles. These nanoparticles include a polymeric organic matrix, at least one light emitter distributed within this matrix, a stabilizing agent, and at least one metal particle enclosed within the matrix, wherein the metal particles are plasmonic nanoparticles. The present disclosure further relates to methods of manufacture and to uses of such nanoparticles.
