摘要：

Site-selective laser spectroscopy at low-temperature is used to analyse the fluorescence of Cr3+ in the non-stoichiometric green spinel MgO-2.6 Ala(2)O(3). Four main kinds of sites are characterized: several more or less distorted strong crystal field sites responsible for E-2 --> (4)A(2) emission lines around 690 nm with lifetimes of 20 to 5 ms and E-2 Splitting of 26 to 120 cm(-1) Cr3+ pairs emitting at about 710 nm, and medium and weak crystal field sites responsible for T-4(2) --> (4)A(2) broad band emissions at about 750 nm and 910 nm, respectively.
