Two dimensional island arrays and honeycomb patterns consisting of ZnO nanocrystal clusters were fabricated on predefined TiO(2) seed patterns prepared by vacuum free, aerosol assisted wet-chemical synthesis. The TiO(2) seed patterns were prepared by applying an aerosol of a water soluble titanium complex on hexagonally close-packed polystyrene bead arrays for different lengths of time. Scanning electron microscopy revealed that a dot array grows into a honeycomb shape as increasing amounts of the precursor were deposited. ZnO nucleation on substrates with a dot array and honeycomb patterns resulted in the formation of two discrete patterns with contrasting fill fractions of the materials.
二维岛状阵列和由 ZnO 纳米晶体簇组成的蜂巢图案是在通过真空无、气溶胶辅助湿化学合成制备的预定 TiO2 种子图案上制造的。TiO2 种子图案是通过将水溶性钛络合物的气溶胶施加到六方密堆积聚苯乙烯珠阵列上来制备的，施加时间不同。扫描电子显微镜显示，随着前体沉积量的增加，点阵列会生长成蜂巢形状。在具有点阵列和蜂巢图案的衬底上进行 ZnO 成核，导致形成具有对比材料填充分数的两种离散图案。
