TbW10-Agarose柔性自支持绿光薄膜的制备及化学响应荧光开关性能研究

论文摘要

基于功能互补原理,以稀土多酸Na9TbW10O36(TbW10)为发光功能组分、琼脂糖为成膜基质,通过溶胶–凝胶及Casting技术制备了稀土多酸柔性自支持绿光薄膜TbW10-Agarose,利用FT-IR、Raman光谱对薄膜的组成及结构进行表征,利用SEM、AFM和TEM对薄膜的厚度、表面粗糙度和微结构进行研究,考察TbW10掺杂量对薄膜透光率及发光性能的影响。在HCl/NH3刺激下,实现了TbW10-Agarose绿光薄膜可逆的化学响应荧光开关性质,利用荧光动力学方法对绿光薄膜化学响应荧光开关的响应时间及可逆性进行研究;并拓展了该绿光薄膜对HCl气体的荧光光谱检测,检出限为0.2731 mmol·L–1。
