具有高纵横比的氧化锌纳米柱阵列，如图所示，是使用聚合物模具在低温下从水溶液中制备出来的。纳米管的形状和尺寸可以通过对聚合物模具进行适当的图案化来调整。正如光子能带结构计算所预测的那样，六角形氧化锌纳米柱阵列在可见光波长处显示出光子带隙。
ZnO nanopillar arrays with high aspect ratios, such as the one shown in the figure, are fabricated from aqueous solutions at low temperatures using a polymer mold. The shape and dimensions of the nanopillars can be tuned by appropriately patterning the polymer mold. A hexagonal ZnO nanopillar array shows photonic bandgaps at visible wavelengths, as predicted by photonic band structure calculations.
