摘要：

Aluminophthalocyanines were encaged in different silica xerogel matrices. Nonlinear reverse-saturable absorption behavior was observed for both nanosecond and picosecond pulse excitation at 532 nm. In order to determine the relaxation paths of the molecules after optical excitation, we measured the evolution of the transmission of a continuous probe beam through the samples following absorption induced by a pump pulse. The transmission recovery was a few tens of microseconds. The fluorescence lifetime was about 10 ns.
