Depending on the ionic radius of the rare earth ions, orthoborates exhibit three di4erent crystalline forms noted LnBO 3 and H-LnBO 3 . A comparative study of the stability relationship of H-LnBO 3 borate (Ln β«Ψβ¬ La, Nd, Sm, and Eu) versus the temperature and synthesis method (solid state reaction a
