| 摘 要： | 对亚波长纳米微结构-非紧密堆积多晶胶体晶体光学薄膜的增透特性进行了研究。采用浸渍-提拉法在玻璃表面组装了亚波长纳米微结构,并利用等效介质理论分析其光学性质,理论和实验符合。研究表明实验制备的纳米微结构具有优异的增透性质,通过控制组装条件可以控制膜层厚度实现高增透效率从可见光到近红外的有效调谐,且微结构在玻璃基底上的等效折射率接近1.22,透射率最大能提高约7%,达到99.8%的增透效果。

| Abstract: | The paper studies the optical performance of a new sub-wavelength nanostructure which consists of non-close-packed polycrystalline colloidal crystals fabricated by dip-coating. Effective medium theory (EMT) is used to analyze the optical property of the as prepared structure. The structure exhibits excellent transmission performance. It can turn the maximum transmission wavelength from visible light to infrared wave by different withdrawal speed. The structure can be used for antireflection coating, and the measured effective refractive index is 1.22, and the maximum transmission of a glass substrate is increased to 99.8%. |
