Inelastic neutron scattering on hydride perovskites MLiH3 and MLiD3 (M = Sr, Ba)

Abstract: Recently, a new class of light emitting materials was discovered. When europium is doped into metal-hydrogen compounds, so-called metal hydrides, such materials emit bright yellow, green or red light when excited by UV radiation. At low temperatures the emission spectra of europium doped SrLiH3, BaLiH3 and the corresponding deuterides exhibit surprising features, which suggest coupling to vibrations of the lattice of the solid compounds. Inelastic neutron scattering experiments are being proposed, which will help to prove this coupling of the luminescence (emitted light) to lattice vibrations. This will help in the understanding of the origin of the light emission in this new class of luminescent materials and to tune the wavelengths for possible lighting application. Such inelastic scattering experiments can best be performed at the instrument TOSCA at ISIS.
