Optical Properties of the Self-Assembling Polymeric Colloidal Systems

Figure 17

A schematic illustration of the colloidal crystal laser (CCL) proposed by Furumi et al. A light-emitting planar defect of Rhodamine (Rh)/PEG-DA is sandwiched between a pair of CC films of PS particles stabilized in PDMS elastomer. The left-hand picture represents a cross-sectional scanning electron microscopy (SEM) image of the magnified light-emitting planar defect between the PS/PDMS CC films. The white scale bar represents 2 μm [18].
