“…A profound effect on properties of materials may be exerted by the size of particles and crystallites of phases that form them, especially with the transition into nano-scale range of their values [47][48][49][50][51][52][53]. It should be noted that, as shown in [31-35, 42-46, 50, 51, 54], the influence of synthesis methods and conditions on properties is specifically great for nanocrystalline materials.…”

Nanocrystalline particles on the basis of La 2 (Ni,Mn,Fe) 2 O 6 variable composition phases of a double perovskite structure have been produced by glycine-nitrate combustion. The size of crystallites grows from 5 to 45 nm with an increase in iron content of synthesized particles. It is demonstrated that iron unevenly builds into octahedral sites of nickel and manganese ions substituting mainly manganese ions. At the same time, the dependence of double perovskite unit cell volume on the iron ions concentration is well described by Retgers' law. KEYWORDS double perovskite, nanocrystals, solution combustion, photovoltaics. ACKNOWLEDGEMENTS The authors express their gratitude to V. V. Gusarov for the attention he paid to the work. X-ray diffraction and SEM was performed using the equipment of the Engineering Center of Saint Petersburg State Institute of Technology.

“…One of the promising methods of synthesis of complex oxides is the method of glycine-nitrate combustion [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65]. At the same time, this method not always guarantees the possibility of one-stage synthesis of complex oxide phases [22,28,32,33,46,58].…”
