介绍了在胶体晶体内外书写的两种光子聚合特征的制备和表征。介绍并开发了双光子聚合（TRP）响应图，以映射通过调制光束光栅编写的特征的聚合和损伤阈值。首次证实了三[4-（7-苯并噻唑-2-基-9,9-二乙基芴-2-基）苯基]胺（af350）作为TPP引发剂，TPP反应图说明了聚合窗口。这些图还表明，胶体晶体内部和外部的聚合行为是相似的，电子显微镜显示几乎相同的分辨率。荧光共聚焦显微镜进一步实现了自组装光子晶体内非自支撑的三维TPP特征的可视化。最后，从胶体晶体内写入的双光子特征中收集微斑光谱，并与模拟结果进行了比较。
The fabrication and characterization of two photon polymerized features written within and outside of colloidal crystals is presented. Two-photon polymerization (TRP) response diagrams are introduced and developed to map the polymerization and damage thresholds for features written via modulated beam rastering. The use of tris[4-(7-benzothiazol-2-yl-9,9-diethylfluoren-2-yl)phenyl]amine (AF 350) as an initiator for TPP is demonstrated for the first time and TPP reponse diagrams illustrate the polymerization window. These diagrams also demonstrate that the polymerization behavior within and outside of colloidal crystals is similar and electron microscopy reveals nearly identical resolution. Fluorescence confocal microscopy further enables visualization of non-self-supporting, three-dimensional TPP features within self-assembled photonic crystals. Finally, microspot spectroscopy is collected from a two photon feature written within a colloidal crystal and this is compared with simulation.
