ABSTRACT
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. © 2004 American Institute of Physics.
