Spectral properties of Cr3+ in SrLaGaO4 under high hydrostatic pressure.

J. Barzowska, M. Grinberg, Y.R. Shen, A. Pajączkowska


In this contribution the absorption, excitation and luminescence spectra of SrLaGaO4:Cr3+ at different temperatures and pressures are presented. It was found that luminescence related to 2E->4A2 transition in Cr3+ shifts with pressure to the red region. The pressure shifts of the luminescence related to 2E->4A2 transition and phonon sidebands are estimated.
