F. Tao et al., SYNTHESIS AND SPECTROSCOPIC CHARACTERISTICS OF LIMGALF6-RE3+ (RE = EU, TM, GD), Physica status solidi. a, Applied research, 165(1), 1998, pp. 303-308
Polycrystalline samples of single phase LiMgAlF6:RE3+ (RE = Eu; Tm, Gd
) are prepared by the solid state reaction method using the ratio 120/
110/100 of LiF/MgF2/AlF3 at 1008 K for 4 h in flowing Ar atmosphere. T
heir structures and spectroscopic characteristics are investigated and
discussed.
