title: Colloidal Silica as a Standard for Measuring Absolute Fluorescence Yield.
abstract: The use of colloidal silica as a standard for fluorescence efficiency measurements is proposed. Its advantages over glycogen as a standard are availability, purity, and stability. Absolute fluorescence yields are reported for a number of stubstiances and compared with values in the literatUre.
