ResumoA series of crystalline perovskite nanoparticles (Ca1–xSrxTiO3, 0 ≤ x ≤ 1, see Figure) has been prepared using a simple, scaleable, molten-salt synthesis method. The generated nanoparticles change from cubes to quasispheres with decreasing x values. Typical nanoparticles have sizes between 70 and 110 nm, irrespective of the Sr or Ca content. The strategy is applicable to the nanoscale growth of other complex oxide materials that exhibit interesting electronic and optical phenomena.
