Abstract
We successfully developed a novel elasticoluminescent (EML) material with water resistance, CaAl2Si2O8:Eu2+ (CAS). The crystal structure, photoluminescence (PL) and EML properties were characterized for both CAS and the typical EML material SrAl2O4:Eu2+(SAO). Contrary to SAO, CAS showed superior water resistance property. No changes were found in the XRD patterns, and the PL, EML intensities, during the whole examination of water immersion test.
