Kurzbeschreibung (Abstract)
Transient light-induced absorption in the near infrared (IR) and visible (vis) spectral range is observed in transparent lanthanum-modified lead zirconate titante piezoelectric ceramics by means of a pump-and-probe-type experiment after pulsed illumination with 532 nm. Its temporal behavior in the IR range is satisfactorily described by a single stretched exponential function, whereas in the vis range a sum of two stretched exponential functions is necessary. The results prove the existence of at least two defect levels in the energetic band gap.
