Abstract
We have measured the radiative quantum efficiency (QE) of the ruby fluorescence using a novel photoacoustic technique. The technique requires the measurement of the phase of the photoacoustic signal as a function of chopping frequency, and is applicable to systems with a simple decay scheme and a sufficiently long fluorescence lifetime. The measured value QE=0.900.05 is consistent with several previous optical measurements.This publication has 16 references indexed in Scilit:
