Synthesis and characterization of ZnS/SiO2 photonic dots
In this report, a facile, low-cost, and effective method has been employed to produce highly monodisperse colloids photonic materials ZnS QDs/SiO2 were fabricated using chemical condensation reactions on poly-methyl methacrylate. The obtained results exhibit whispering gallery emission modes with 1.47nm spacing. In addition, the emission from ZnS QDs was modulated by a spherical microcavity. Furthermore, the spherical cavity dimension was calculated using the relation between modes spacing and cavity dimension and found to be 11.86 m.
