Preparation, electronic structure of gadolinium oxyhydride and low-energy 5d excitation band for green luminescence of doped Tb3+ ions

Oxyhydride compounds of GdHO and GdHO:Tb3+ were successfully prepared by solid state reaction of GdH3, Gd2O3 and Gd2O3:Tb3+ under a H2 atmosphere. XRD analysis suggests that GdHO has a cubic fluorite structure (space group Fm3m, lattice parameter a = 5.38450(4) Å for GdHO and 5.38523(6) Å for GdHO:T...
