Abstract

The absorption, luminescence and excitation electronic spectra of MgSiO3 doped with chromium were measured in the visible and near infrared regions at temperatures down to 10 K. The optical spectraare composed of both broad bands and sharp lines, showing the presence of Cr3+ substituting for both non-equivalent Mg2+ ions in distorted octahedral sites of high and low ligand field strength respectively. All the spectral features were assigned and a preferred occupation of the low field sites was evidenced. © 1993.
