We demonstrate two-color nano-emitters that enable the selection of the dominant emitting wavelength by varying the polarization of excitation light. The nano-emitters were fabricated via surface plasmon-triggered two-photon polymerization. By using two polymerizable solutions with different quantum dots, emitters of different colors can be positioned selectively in different orientations in the close vicinity of the metal nanoparticles. The dominant emission wavelength of the metal/polymer anisotropic hybrid nano-emitter can thus be selected by altering the incident polarization.
