利用荧光显微镜和相衬显微镜观察了在固体表面以高密度、高取向方式填充荧光和非荧光聚苯乙烯乳胶颗粒（3,1,0.5 μm）的复合二维球形阵列中的光传播。此外，通过聚焦，我们能够直接确定堆叠模式，例如，面心立方填充或六边形紧密填充，最多三层。传播模式可分为两种：一种是在粒子内部传播，另一种是在粒子表面传播。这两种模式的贡献似乎取决于相对光频率。
Light propagation in composite two-dimensional spherical arrays in which mixtures of fluorescent and nonfluorescent polystyrene latex particles (3, 1, 0.5 μm) are packed in a highly dense, highly oriented manner on a solid surface was observed by use of fluorescence microscopy and phase-contrast microscopy. In addition, by means of through-focusing, we were able to determine directly the stacking mode, e.g., face-centered-cubic packing or hexagonal close packing, in up to three layers. The propagation modes can be divided into two types: one inside the particles and the other on the particle surfaces. The contribution of these two modes appears to be dependent upon the relative light frequency.
