Determination of Lifetime of Ce3+ Luminescence by Time-Correlated Single Photon Counting Method during Sonoluminescence from Aqueous CeCl3 Solution

Using a counter for single photon correlations, the flashes of sonoluminescence and sonophotoluminescence of a 0.1 M aqueous solution of CeCl3 are separated by time. The lifetime of Ce3+ luminescence is determined by the correlation method as equal to 33 ns, which corresponds to the value measured by the traditional methods of time-resolved spectroscopy. The shape of the luminescence flash-namely, the exponential decay-is confirmed by numerical simualtion of the correlation function.

Automated summary

The experiment separated the flashes of sonoluminescence and sonophotoluminescence of a 0.1 M aqueous solution of CeCl3, and determined the lifetime of Ce3+ luminescence as 33 ns using the correlation method, confirming the exponential decay shape through numerical simulation of the correlation function.
