Abstract
Disclosed is a synthesis method for preparing tantalum pentoxide colloid including the steps of: a. Providing a transparent solution of amorphous tantalum pentoxide, b. Subjecting the solution to solvothermal conditions in order to form tantalum pentoxide nanocrystals, c. Dispersing the tantalum pentoxide nanocrystals in a solvent so as to form a tantalum pentoxide colloid.
