Abstract
Sm3+ or Dy3+:LiYNbO3 ceramic powders have been synthesized by a solid-state reaction method to study their photoluminescence properties in order to evaluate emission performance. Upon exposure to the UV lamp, these luminescent ceramic powders have displayed a bright reddish-orange (4G5/2→6H7/2) (Sm3+) and an yellow (4F9/2→6H13/2) (Dy3+) color emissions, respectively. In addition, these phosphors have also been characterized for their structures and morphology from the measurement of X-ray diffraction (XRD), Fourier transform-infrared (FTIR), scanning electron microscope (SEM), EDAX, thermogravimetry (TG) and differential thermal analysis (DTA) results.
