Abstract
The object of the study was samples of commercial piezoelectric ceramics Pb0.95Sr0.05(Zr0.53Ti0.47)O3+1% Nb2O5 (PZT-19). A series of experimental studies of the kinetics of changes in the optical transmittance of the PZT-19 ceramic samples was carried out during exposure to the full spectrum of a PESL-SF2 11 W/865 E14 fluorescent lamp. The kinetics of restoring the initial optical transmittance of samples stored in the darkness after the light exposure was studied as well. The effect of thermal annealing of samples on the erasure of a photochromic-induced color change induced by irradiation revealed.
