Abstract
Nanosecond laser photolysis of poly(N-vinylcarbazole) film did not give any appreciable transient absorption above an excitation intensity of 25 mJ/cm2. Only a tail of the ground-state absorption was observed, which was analyzed to estimate the temperature below, at, and above laser ablation threshold (60 mJ/cm2). The temperature rise time was less than 50 ns, and the film cooled in a few microseconds. The maximum temperature attained at the excitation intensity just below the threshold was close to the decomposition temperature of the film.
