N2 - Laser excitation at different wavelengths was carried out on Cr3+-doped transparent glass-ceramics of composition (mole%) Ac(58.7SiO2, 16.7 Al2O3, 17.8 MgO, 6.7TiO2, 0.03 Cr2O3) and Bc(49.1 SiO2, 19.7 Al2O3, 21.9 MgO, 6.0 TiO2, 3.2 ZrO2, 0.03 Cr2O3), and in synthetic crystals of composition MgAl2O4 (Cr3+), Mg2TiO4 (Cr3+) and Mg12 Ti02 Al16 o4 (Cr3+). Analysis of the emission spectra, excitation spectra and decay curves at 4.4. K and room temperature reveals that Cr3+ is essentially situated on distorted single sites and in pairs exchanging Al3+ ions in the crystalline phase of glass-ceramics.
