The concept of nanophotonic droplets, which are individual spherical polymer structures containing accurately coupled heterogeneous quantum dots, has been previously demonstrated. Such combinations are theoretically promising for their ability to induce novel optical functions. In this paper, we focus on the implementation of wavelength conversion as one of the fundamental optical functions of nanophotonic droplets. A novel mechanism involved in the formation of nanophotonic droplets and results of experimental verification of wavelength conversion using formed nanophotonic droplets are described. By a quantitative comparison with a corresponding sample consisting of randomly dispersed quantum dots, the effectiveness of proposal was successfully demonstrated.
