Rare-Earth Doped Piezoelectric Materials

Physics

The mechanical industry, medical imaging, electronic information, ultrasonic devices, and other fields use piezoelectric materials including ceramics, crystals, and films extensively. Generally, improving the electric characteristics of piezoelectric materials involved adding oxide dopants or introducing new solid solutions to produce the morphotropic phase boundary. Due to their multifunctional performances combining piezoelectric and photoluminescence properties, rare-earth element doped piezoelectric materials have received a lot of attention recently. These materials have potential applications in the fields of optoelectronics, electronics, automatic control, machinery, and ultrasonics. On rare-earth doped piezoelectric ceramics, single crystals, and films, a summary of recent research and viewpoints was given.
