摘要:

The excitation of a fluorophore by rapidly varying fluctuations in a free‐running argon‐ion laser is shown to produce variations in measured fluorescence. The power spectrum of the fluctuations can yield lifetime information on luminescence and the experimental apparatus described exploits this phenomenon. Methods of improving the measurements are also considered.
