5.3 Conclusions

(1)In the present work, the Dy, Mn, or Gd-doped NaCaPO phosphors have been synthesized by the conventional solid-state reaction method. The formation of this compound was confirmed by the XRD technique. SEM images show foam-like morphology with average crystallite size in the submicrometer range.

(2)The emission spectrum of NaCaPO:Dy (at 386 nm excitation) has two intense broad band centered at 480 and 573 nm, which correspond to blue and yellow regions of the visible spectrum, respectively. These two emissions could be used for the development of white LEDs.
