摘要: 从光化学反应动力学模型出发,推导出一个新的荧光猝灭动力学方程:I0/I=1+APQB,实验结果表明:该方程能够准确地拟合荧光反应的实验数据,可用于定量描述猝灭剂对高分子半透膜内的荧光分子的影响,并能很好地说明荧光猝灭的机理。

Abstract: According to the kinetic model of optical chemical reactions,a new kinetic equation is deduced as the following: I0/I=1+APQB As a simple and prastical kinetic equation, it can be used to determine quantitatively a gasous or liquid quencher quenching a luminescent complex immobilized in some polymer matrix.The experimental results show that the equation can be fitted with the luminescentquenching data and be used to explain the common mechanism of luminescent quenching reactions in a polymer matrix very well.
