| Abstract: | The photothermal deflection spectroscopy(PDS) is applied to absolute quantum yield determination for nile blue and naphthol blue. The principle and experimental results are described. The PDS is an alternating single testing technique. It has remarkable adrantages over conventional photometric method in that it can immu- nize from interference, and can simplify process of adjustment and measurement, and has less instrumental error. It is suitable to determine absolute quantum yield of new fluorescent standard. |
