WebFeb 7, 2011 · Abstract. A substantial increase in photoferroelectric image storage sensitivity has been achieved in ferroelectric-phase PLZT ceramics by implanting protons (H + ions) into the image storage surfaces. The 10- to 100-fold increase in sensitivity is attributed to increased densities of carrier photoexcitation and trapping centers and to an increase in …
