Abstract: (2022 Views)
In this work, suspension polymerization is applied to fabricate monodisperse polymethylmethacrylate (PMMA) microspheres with different diameters and the effect of the polymerization initiator’s concentration on the size of the microspheres is studied. Then, the artificial opal photonic crystals are fabricated with PMMA microspheres using the vertical deposition via evaporation induced self-assembly method. Furthermore, the size of the microspheres and optical properties of opals are investigated. It is shown that the concentration of the polymerization initiator plays a key role in specifying the size of the polymer microspheres and consequently the optical properties of the opal photonic crystals.
