Photostriction in Lead Lanthanum Zirconate Titanate Ceramics Enhanced by the Additive Effect

Abstract

We have investigated the photostriction response in the PLZT ceramics doped with various amounts of Ta and subsequently heat-treated in nitrogen. Both photovoltaic and piezoelectric properties were improved by doping with Ta. On the other hand, nitrogen-treatment heightened the photovoltaic response, but scarcely affected the piezoelectric parameters. By the combined effect of doping with Ta and nitrogenmtreatment, the photostriction response was confirmed to be markedly enhanced.
