中文摘要：

通过本体溶胶-凝胶方法制备了含6＇-哌啶-1，3，3-三甲基螺[吲哚-2，3＇-[3H]萘-[2，1-b][1，4]噁嗪]的光活性SiO2凝胶。光栅生长曲线显示该光活性凝胶具有快速光响应。在紫外光的预激发下用He-Ne激光器写入光栅时衍射效率的变化规律显示螺噁嗪的光致变色有光致构造异构和光致顺反异构两个竞争过程。通过紫外激发光源的开启和闭合对实时全息光栅的衍射信号进行了调制。

英文摘要：

Monolithic SiO2 doped with 6＇-piperidino-1,3,3-trimethylspiro [ indolino-2, 3＇- [ 3 H ] naphtha-[ 2, 1-b][1,4]oxazine] was prepared via bulk sol-gel process.Real-time holographic gratings were optically recorded with a pair of interferential He-Ne laser beams （632.8 nm） with pre-irradiation by ultraviolet light. The grow curve of holographic gratings indicates that the photo-active gel has fast photoresponse. The change in diffraction efficiency indicates that the photochromism of spirooxazine exhibits a competing process between photo-orientation and photo-isomerization. Reversible holograms were recorded in the medium by modulating UV light.
