ceramics were prepared using a conventional solid-state reaction technique. Multiple functions of electrostriction and photoluminescence were realized in the ceramics. Red emission (614 nm) was observed in the samples, and the intensity reached its largest value in the sample of 40 mol% Sr addition. Although the electrostrictive strain decreased in the Pr and Al doped samples, the temperature dependence is remarkably improved comparable to the undoped sample
