Electroluminescent ceramics excited by low electrical field
Strong green-light emission occurs in Eu:SrAl₂O₄ ceramics and Eu:SrAl₂O₄ /poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) composites when excited by a lower dc or ac voltage. That emission is caused by strong electric-mechanic-optic interaction. The composite shows stronger luminescent emission intensity in comparison to similar ceramics because of an enhanced piezoelectric effect from P(VDF-TrFE)—a typical piezoelectric polymer.
