| description | An extensive experimental study of trivalent iron (Fe<sup>3+</sup>) ions in orthorhombic lithium gallate nanocrystals was undertaken. Various spectroscopic methods, such as Raman spectroscopy, extended X-ray absorption fine structure, the Mössbauer effect, electron paramagnetic resonance, photoluminescence, thermoluminescence, and cathodoluminescence were used to investigate the synthesized phosphor. This study revealed the existence of multiple Fe<sup>3+</sup> sites, out of which the tetrahedral sites are preferentially occupied. Extensive optical studies showed that the Fe<sup>3+</sup> doped lithium gallate phosphor is a promising candidate for various luminescence and thermoluminescence-related applications in the near-infrared regime. |
