摘　　要：本文利用激光诱导热透镜效应,采用比较方法,简便而精确地测量了激光染料稀溶液的绝对荧光量子效率。The paper presents laser induced thermal lens effect which makes the simple and precise measurements of absolute fluorescence quantum yield for dilute laser dyes solutions. We use a comparison method to determine the quantum yields of fluorescence sample nile blue, cresyl violet and oxazine-1 perchlorate dyes in ethanol at concentration below 10^(-5)M. These yields are 0.47±0.06, 0.49±0.06 and 0.15±0.02, respectively.
