Investigation of the pulsed electron and laser irradiation of PLZT ceramics using laser scanning confocal microscopy

Results of the measurement of Raman scattering spectra (RSS) using the laser scanning confocal microscope (LSCM) with the excitation line λ = 441.6 nm of the relaxor PLZT 8/65/35 ceramics irradiated by different doses of laser and high current pulsed electron beams are given. The two-dimensional images and layered scanning data for unirradiated and irradiated parts of the sample were obtained using the Raman-active mode $v_{TO_4 } $ = 536 cm^?1. Space regions with an anomalously high intensity of the $v_{TO_4 } $ mode were found in the irradiated sample. Possible mechanisms of the effect of high current pulsed electron irradiation for the PLZT 8/65/35 are discussed.
