Abstract

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.
