It has long been postulated that phenomenon of light emission upon fracture-induced excitation,termed triboluminescence,is related to the piezoelectric effect in crystal lattices.
Eu2+activated fluorophosphate Ba3LnNa(PO4)3F(Ln = Gd,Y)with blue and red double-color emitting phosphors were synthesized by a solid state reaction in reductive atmosphere.
