Luminescent polymer–electrolyte nanocomposites containing nanoparticles as luminescent centers have been produced. Europium-doped zinc oxide nanoparticles were used, which were grown in-situ in a poly(ethylene glycol) matrix. Under ultraviolet irradiation between 320 and 380 nm, the emission color of the composite varies in the blue–yellow region, depending on the ZnO crystal size (see Figure). Red emission was produced under 466 nm excitation.
