Abstract: Hydrothermal synthesis has been successfully used to obtain finecrystalline powders of yttriumaluminum garnet (YAG) doped with manganese ions and codoped with cerium and manganese ions. Usingthe method of hightemperature solidstate synthesis, ceramic specimens of YAG that contain europium andytterbium ions have been obtained. In synthesized YAG:Eu and YAG:Yb ceramics, no luminescence that canbe attributed to 5d–4f transitions in Eu2+ or Yb2+ ions has been detected, even though the scheme of energylevels of these ions constructed with respect to YAG energy bands indicates that there is a potential possibilityof the occurrence of 5d–4f luminescence for Eu2+ ions in YAG. At room temperature, the luminescencespectrum of hydrothermally synthesized YAG doped with manganese ions consists of two broad bands withmaxima at ~600 and ~750 nm and does not contain any narrow bands in the red or IR range. Therefore, thespectrum contradicts to the properties of the luminescence of Mn2+, Mn3+, or Mn4+ ions in YAG describedin the literature, even though the obtained hydrothermal specimens can contain noticeable concentrationsonly of Mn3+ ions.
