Synthesis of anisotropic hybrid nanoparticles containing f-block elements.

摘要

Inorganic-organic hybrids are fascinating since they combine the properties of both individual phases in one material. The organic phase allows chemical modification due to the high diversity of functional groups whereas via the inorganic phase optical, electronic or magnetic properties can be introduced to the material. Very often also synergistic effects are observed. One example are upconversion phenomena that appear when fluorophores are combined with absorbing organics. New or enhanced effects like changing the electronic properties can evolve, as the hybrids are reaching a confined state. One versatile approach to synthesize nanostructured hybrid materials is the nonaqueous sol-gel route based on benzyl alcohol.1 Many metal precursors are established so far, but are mainly containing d-block metals. Rare earth metals are known for strong and outstanding magnetic, electronic and optical properties.
