摘要
We describe a novel general method for synthesizing monodisperse colloidal perovskite particles at room temperature by postsynthesis addition of metal hydroxides to amorphous titania colloids.In previous work, we used titania particles to synthesize homogenously mixed silica-titania composite particles by addition of a silica precursor to the titania particles (Demirors et al. Chem. Mater., 2009. 21, 979). Here we show that the principle is general and can be used to prepare different titania-based composite beads. We demonstrate the synthesis of colloidal perovskites like BaTiO3, SrTiO3, CaTiO3 and Ba0.5Sr0.5TiO3, which have importance for the electronics industry for their dielectric properties. Mixed perovskites like BaxSr1-xTiO3 bring tunability in structure and properties by changing the ratio of metal cations. We also show fabrication or metal core, BaTiO3 shell particles, which could find applications in percolative capacitors, and luminescence properties or Pr3+ doped colloidal perovskites.
