Abstract:
A method of depositing rare-earth boride onto the surface of a substrate comprising the steps of:a. dissolving borane and at least one rare-earth halide in an organic solvent;b. providing and placing a substrate in said solution of borane and at least one rare-earth halide in said organic solvent, so that a surface of said substrate is submerged but accessible by electromagnetic radiation;c. providing a source of electromagnetic radiation and exposing the surface of said substrate to electromagnetic radiation through said solution of borane and at least one rare earth halide in said organic solvent, from said provided source of electromagnetic radiation;such that said at least one rare-earth halide in the vicinity of said substrate surface is fragmented into free halide and free rare-earth components, with the result being that said free halide fractures said borane, with the further result being that components of said fractured borane combine with free rare-earth to form rare-earth boride which deposits on said surface of said substrate.
