We also conclude that the sharp peaks at a diffraction angle of 20.1°, 28.5°, 29.3° and 35.1° are stronger. Contrast to the JCPDS standard card (No. 34–0379), con- firmed that the sharp peaks correspond to the diffraction peaks of SrAl2O4:Eu2+,Dy3+. The result indicated that
the addition of the luminescent material does not affect the crystal lattice of the polymer. Substantially, this en- sures the brightness of rare earth luminescent material in the nonwoven.
