Abstract
Time-resolved luminescence spectra obtained upon a UV-laser ablation of Bi-Sr-Ca-Cu-O superconducting materials were measured with nanosecond time resolution. In the early delay times after the irradiation, a wide continuum spectrum with self-absorption lines due to the electronic transitions from the ground states of Ca+, Sr+, and Sr was observed. The continuum emission decayed with the lifetime of 70 ns and was replaced by emission lines of Ca+, Sr+, Ca and Sr which had decay times of around 1μs.
