Solvothermal synthesis and characterisation of La1-xAxMnO3 nanoparticles

The synthesis of La(1-x)A(x)MnO(3) (A = Ca, Sr, Ba) nanoparticles in nonaqueous solvents has been studied. For this solvothermal procedure benzyl alcohol and acetophenone were chosen as reaction media. After this treatment in mild conditions a precipitate was obtained, which, however, can be annealed to the crystalline perovskite structure. Our results show that acetophenone is more suited to obtain the clean pervoskite phase than benzyl alcohol. (c) 2006 Elsevier Inc. All rights reserved.
