We analyze, using the fluorescence spectroscopy of Eu3+, two partially disordered crystals from the langasite family:
langasite and langatate. There are two main differences between these crystals: (a) the randomly occupied positions (Ga3+
- Si4+ in tetrahedral positions for langasite and Ga 3+ - Ta 5+ in octahedral positions for langatate) and (b) the charge
difference between the ions in these positions (1e for langasite and 2e for langatate). For LGS:Eu, the presence of multiple
fluorescent centers could not be evidenced, while for LGT:Eu the splitting of the fluorescence lines clearly indicates the
presence of multiple fluorescent centers.
