The strontium lanthanum aluminate SrLaAlO4 (SLA) crystallizes in the perovskite-like K2NiF4 structure (a = b = 3.756 Å, c = 12.64 Å) with space group I4/mmm[1] and belongs to the group of materials with the general chemical formula ABCO4, where A = Ca, Sr or Ba, B = Y or some other rare earth metal, and C = Al, Ga or some transition metal[2] (and references therein).

Doping of manganese ions could give a number of interesting properties of the materials as for holographic recording and optical data storage, laser light optical limiters, thermoluminescent dosimetry, fluorescent thermometry or thermoluminescent screens for visualization of local heating of various origin, including heating by IR laser light.

The nanosized powder of SrLaAlO4 doped with 0.02 at% Mn ions was obtained by modified sol-gel method (Pechini). The solution with acetic acid as complexing agent and ethylene glycol as polymerizing agent was used. The xerogel was dried at 150°C for 12 h and then grinded in an agate mortar to obtain fine powder. The powders were annealed at different temperatures in the air atmosphere. The single phase compound of SLA structure was obtained.

The size and morphology of nanocrystals were analyzed by high resolution scanning electron microscopy (HRSEM) with LEO GEMINI 1530 apparatus. Identification of crystalline phases in samples was made by X-ray diffraction (XRD) using a Siemens D-500 powder diffractometer with CuKα radiation at the wave length λ= 1.5418 Ǻ.
