  Germanium tetra(tertiary butoxide): Synthesis, structure and its utility as a precursor for the preparation of europium doped germanium oxide nanoparticles

  摘要：

  Germanium tetra(tertiary butoxide), [Ge((OBu)-Bu-t)(4)], has been prepared by the reaction of GeCl4 with KOBut in benzene. It is a monomeric crystalline solid having a distorted tetrahedral configuration, defined by the coordination of four OBut groups around germanium atom. The TG analysis showed that the compound is thermally stable and volatilizes at around 130 degrees C. Europium doped and un-doped germanium oxide nanoparticles were prepared based on the urea hydrolysis of Ge((OBu)-Bu-t)(4)/Eu(OOCCH3)(3) in ethylene glycol medium at 150 degrees C followed by heating the resulting product at 750 degrees C. The nanoparticles were characterized by XRD, TEM and PL measurements. The europium doped nanoparticles, which were nearly monodispersed (similar to 30 nm), showed luminescence and the Eu3+ ions were occupying the surface of the GeO2 nanoparticles. (c) 2010 Elsevier B.
