Abstract

Fabrication of honeycomb-patterned microporous films (honeycomb films) by casting dilute solution of several types of polymers under high humidity has been already reported. In order to realize photofunctional materials, composites were formed by introducing mixture of two kinds of luminescent monodisperse nanoparticles (NPs) into micropores of the PMMA honeycomb film fixed on a substrate. Thickness of the honeycomb film was controlled by exposure of the PMMA film to ozone gas for appropriate hours. As indicated in Figure, single-layered hexagonal arrays of NPs were formed in the micropores of the composites. Average diameters of NP and micropore are 1.0 μm and 3-4 μm, respectively. Composites with different NP diameters and different micropore sizes have been fabricated to control number of NPs in a micropore. Emission spectra of the individual micropores will be measured.
