description

The comprehensive study of high-current pulsed electron irradiation effect on the structure and lattice dynamics as well as Atomic Force (AFM) and Laser Confocal Scanning microscope (LSCM) surface imaginaries of PLZT 8/65/35 ceramics have been performed. X-ray powder diffraction studies show the transformation of the cubic perovskite Pm-3m (Z = 1) into orthorhombic Pmmm (Z = 1) structure for the sample irradiated by one pulse (dose 6 × 1014 electrons/cm2) and into cubic Pm-3m with increased lattice volume and more ordered structure at irradiating by 10 and 100 pulses (dose 6 × 1015 and 6 × 1016 el/cm2). A consequence, the changes of number, intensity and phonon modes position occur in Raman spectroscopy data. It should be noted that the annealing at 200 °C of the single irradiated sample leads to the partly restoration of the orthorhombic structure. AFM and LSCM surface imaginaries correlate well with X-ray diffraction and Raman measurements. The possible mechanism of pulsed electron irradiation effect in PLZT 8/65/35 ceramics is discussed.
