Synthesis and photoluminescent characterization of ceramic phosphors LiMgGeO:Ln (Ln = Pr or Tm) under different excitation wavelengths.

In the current work, germanate phosphors LiMgGeO:Ln (Ln = Pr, Tm) have been synthesized and then investigated using luminescence spectroscopy. The X-ray diffraction analysis demonstrate that ceramic compounds LiMgGeO containing Pr and Tm ions crystallize in a monoclinic crystal lattice. Luminescence properties of Pr and Tm ions have been examined under different excitation wavelengths.

Synthesis and Characterization of LiMgGeO:Ho.

In this work, the synthesis and characterization of LiMgGeO:Ho ceramics were reported. The X-ray diffraction measurements revealed that the studied ceramics belong to the monoclinic LiMgGeO. Luminescence properties were analyzed in the visible spectral range.
