查询词典 opal

Results of XRD,SEM,and UV-Vis indicated that ZnS nanocrystals can grow in and fill in the void of opal template,and SiO2 microspheres of templates are dissolved so as to form some three dimensional ordered porous structure and to form the inverse opal ZnS photonic crystals. Compared with opal templates,ZnS-opal and inverse opal ZnS photonic crystals assembled with SiO2 spheres in the same diameter show good optical properties and exhibited photonic band gap. The photonic band gap position of inverse opal ZnS moves towards UV area compared with opal and ZnS-opal.

结果表明：溶剂热法多次充填可使ZnS纳米晶在模板密堆积形成的空隙中均匀成核；经过酸处理的ZnS-opal中SiO2微球溶解、坍塌，形成蜂窝状三维有序介孔和反opal结构ZnS基光子晶体；相同粒径SiO2微球组装的opal模板、ZnS-opal以及反opal结构ZnS光子晶体均表现出光子带隙特性，但反opal结构ZnS光子晶体带隙位置相比前两者发生了蓝移。

SiO2 opal with face centered cubic structure is fabricated using a self-assembly method. Two different three-dimensionally ordered macroporous carbon materials are prepared using SiO2 opal as a template through "volume templating" and "surface templating" approaches, respectively. The final morphology of the sample can he controlled by the infiltration times.
