摘　　要：在圆柱基底的曲面上利用垂直沉积法将胶体小球自组装生长为胶体晶体。观察了晶体形貌,搭建了光学测试系统,并对其光学特性进行了表征。讨论了不同实验参数对曲面上胶体晶体生长过程及质量的影响。实验结果表明,在合适的温度和浓度下,在毛细管曲面上制备了高质量的胶体晶体。Colloidal crystals are fabricated on surface of cylinder by vertical deposition technique. An observation is carried out with microscope to characterize surface morphology of crystal and photonic gap is measured with optics test system. The role of evaporation temperature and radius of curvature are investigated. The test result shows that high quality colloidal crystals are fabricated on surface of cylinder at suitable temperature and consistency.
