| 摘 要： | 基于功能互补原理,将Dawson型多阴离子P_2W_(18)O_(62)~(6-)可逆的电致变色性质与Tb~(3+)优异的发光性质相结合,在外加氧化还原电位下实现了P_2W_(18)O_(62)~(6-)@Tb~(3+)混合溶液可逆的电致变色及荧光开关性能,考察外加还原电位对电致变色响应时间及荧光开关能量转移效率的影响,在-0.38、-0.69、-0.85 V下混合溶液的能量转移效率分别为85.97%、87.53%、93.42%。在此基础上,将电化学还原与化学氧化相结合实现了P_2W_(18)O_(62)~(6-)@Tb~(3+)混合溶液对H_2O_2紫外可见、荧光双光谱检测,紫外可见、荧光光谱法对H_2O_2的检出限分别为1.76×10~(-2)、3.04μmol·L~(-1)。
