In the present work we have investigated luminescence properties of the fine, well-crystallized undoped YAG polycrystalline powders and thermochemically treated YAG polycrystalline powders. Presented work give evidence of significant role of 'antisite' defects (AD), i.e., where some portion of one type of cations (Y 3+ ) occupy another cations (Al 3+ Oh ) sites and vice versa in YAG structure, on the creation and structure of luminescence centers in complex multi-component oxides.
