Commentaar over activators en spectra:
Natural diopside displays a large variety of luminescence centers: at room temperature main features are a 450 nm band, that can be ascribed to the TiO6 complex, an intense bands at 585 and 690 nm that can be ascribed to Mn2+ ions in M2 (Ca2+) and M1 (Mg2+) sites, lines near 684 nm belonging to Cr3+ and band peaking at 690 nm ascribed to Fe3+ (Gorobets and Rogojine 2001).
