Bright luminescence is observed for the perovskite KMgH3:Eu2+ and a wide red shift in the emission energies of Eu(ii) in NaMgH3. In LiBaxSr1−xH3:Eu2+ the emission energy depends on the value of x.

AbstractThe ligand field reflectance spectra of octahedrally coordinated Cu2+-ions in different host lattices and at different temperature (300 °K - 4 °K) are critically compared. Especially the band shifts with decreasing temperature are analysed with respect to transitions from a dynamical to a static Jahn-Teller effect (macroscopic Jahn -Teller distortion of the lattice). In addition the square planar coordination of Cu2+ is discussed and alternative descriptions in the crystal field formalism and the angular overlap model are given.
