摘要
利用牺牲模板法制备了SiO2反蛋白石型光子晶体,用扫描电子显微镜对其表面形貌及其厚度进行了表征;并在其孔隙中填充了具有光响应的有机染料分子螺吡喃衍生物,通过紫外-可见反射光谱监测了光诱导下染料分子构型转变过程中光子晶体光子禁带的变化。结果表明在不同波长的光照下,最大反射波长处的反射率可以进行可逆地控制,并实现了光诱导下对染料分子荧光的调控。
SiO2 inverse opal PCs were fabricated by sacrificial template,whose morphology and thickness were characterized by scanning electron microscopy.Photo responsive organic dye spiropyran derivative were infiltrated into SiO2 inverse opal.The change of stopband of inverse opal was monitored by Uv-visible reflection spectra induced by light,in which the dye molecule underwent a reversible configurable transformation.The results demonstrate that the reflectivity of the maximum reflection wavelength can be controlled reversibly,and the fluorescence of dye molecules can also be tuned.
