【Abstract】 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^-5M. These yields are 0.47±0.06, 0.49±0.06 and 0.15±0.02, respectively.更多还原
