Abstract
Official abstract text for this publication.
Lanthanide fluorinated alkoxide derivatives can be synthesized from the alcoholysis reaction of the lanthanide bis-trimethylsilyl amide and an excess amount of hexafluoro iso-propanol. Nanoparticles can be formed from the lanthanide fluorinated alkoxide derivatives by a solvothermal or solution precipitation process.
First claim
Opening claim text (preview).
I claim: 1 . A method to synthesize a lanthanide hexafluoro iso-propoxide derivative, comprising reacting hexafluoro iso-propanol with [Ln(NR 2 ) 3 ], where R═Si(CH 3 ) 3 and Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, or Sc, in an organic solvent to form the lanthanide hexafluoro iso-propoxide derivative. 2 . The method of claim 1 , wherein the organic solvent comprises a non-polar solvent. 3 . The method of claim 1 , wherein the organic solvent comprises toluene. 4 . The method of claim 1 , wherein the organic solvent comprises hexane. 5 . The method of claim 1 , further comprising adding the lanthanide hexafluoro iso-propoxide derivative to a solvent and solvothermal processing the solution at a sufficiently high temperature and pressure to produce lanthanide fluoride nanoparticles. 6 . The method of claim 5 , wherein the solvent comprises a high boiling point amine. 7 . The method of claim 6 , wherein the solvent comprises trioctylamine. 8 . The method of claim 6 , wherein the solvent comprises pyridine. 9 . The method of claim 5 , wherein the temperature is greater than 150° C. 10 . The method of claim 1 , further comprising adding the lanthanide hexafluoro iso-propoxide derivative to a solvent and heating the solution at a sufficiently high temperature to precipitate lanthanide fluoride nanoparticles. 11 . The method of claim 10 , wherein the solvent comprises oleylamine or hexadecylamine. 12 . The method of claim 10 , wherein the temperature is greater than 280° C.
