Optical absorption in ionhyphen;implanted lead lanthanum zirconate titanate ceramics

摘要

Optical absorption measurements have been performed on unmodified and on ionhyphen;implanted lead lanthanum zirconate titanate ceramics using the photothermal deflection spectroscopy technique. Bulk absorption coefficients depend on the average grain size of the material while the absorption associated with the ionhyphen;damaged layers does not. The damagehyphen;induced surface absorptance correlates well with the photosensitivity observed in implanted PLZT devices, supporting earlier models for the enhanced imaging efficiency of the materials.
