Titanium-doped SrAl_0.5Ta_0.5O₃: LaAlO₃ (SAT:LA) perovskite solid solution single crystals were grown by the Czochralski method for two Ti concentrations: 1 wt.% (LSAT1) and 2 wt.% (LSAT2). It was stated that incorporation of Ti into SAT:LA crystal takes place in a non-uniform way. Ti³⁺ ions enter the crystal mainly in its conical part and mainly inside a thin (2-3 mm) layer within the crystal boundary. At room temperature, crystals from the conical part of the boule reveal strong absorption centered at about 529 nm for the case of LSAT1 single crystal while at about 451 and 651 nm for the case of LSAT2. Low temperature measurements have shown two absorption peaks centered at about 489 and 562 nm. Moreover, the 850 nm peak is clearly observed. The intensity of the above described absorption coefficient strongly depends on the dopant concentration and reaches even 80 cm^-1. The above bands seem to be connected with non emitting Ti³⁺ centers. After g-irradiation, additional absorption is observed peaked at about 423 nm which gives two emission bands placed near 400 and 800 nm (375 nm excitation wavelength). They seem to be Ti³⁺ emissions coming from Ti³⁺ ions, occupying two different lattice octahedral positions one of which being octahedral (Al, Ta) site. Blue fluorescence is self-evident.
