E. Lukowiak et al., SPECTROSCOPIC PROPERTIES OF CHROMIUM(III) IONS IN CR-DIOPSIDE CRYSTAL, Bulletin of the Polish Academy of Sciences. Chemistry, 41(3), 1993, pp. 187-197
Optical absorption, IR, Raman and luminescence spectra of Cr(III) in t
he natural diopside crystal were reported. The crystal field parameter
s (D(q) = 1525 cm-1, B = 736 cm-1) were determined. The IR and Raman s
pectra analysis was performed. The intensive broad band luminescence (
centered at 12 700 cm-1) was observed at the room temperature. The opt
ical properties of Cr-diopside were compared with the Cr3+ doped silic
ate glass.
