设计了简易的压强可控自组装实验装置, 制备了由直径为260 nm的聚苯乙烯(PS)胶体球组成的面心立方光子晶体。分析了压强的变化对光子禁带(PBG)深度及光子带隙边缘(PBE)坡度的影响, 确定了合适的压强生长环境(P=5999.5 Pa)。利用该实验装置, 还进行了光子晶体的小批量制备, 一次性制得了三块光子晶体, 并从不同角度对每一块光子晶体的透射谱及不同光子晶体的透射谱进行了测量。同一光子晶体不同位置透射谱的重合、同一批次制备的不同光子晶体透射谱的一致性及光子禁带两侧的Fabry-Pérot振荡等均说明：该装置制备的光子晶体在大区域、大面积上是高度有序、均一和平整的; 利用该实验装置进行光子晶体的小批量制备是可行的。

A facile pressure controllable self-assembly apparatus was designed, and perfect three-dimensional face-centered cubic(FCC) photonic crystals(PCs) were fabricated by using polystyrene colloidal micorspheres with diameter of 260 nm. The effects of pressures on photonic band gap depth and photonic band edge slope were analyzed and the optimal pressure condition(P=5999.5 Pa) for PCs growth was confirmed. Three photonic crystals were fabricated once and their transmittance spectra were measured. The transmittance spectra measured at different positions of the same PC and different PCs are similar. Fabry-Pérot oscillations appear at both sides of the main transmittance valley. PCs fabricated by this experimental apparatus are uniform, similar and highly ordered in the long-range crystal orientation and large areas. The experimental apparatus can be used to fabricate PCs in small-batch.
