| 摘要 |
A layer of a material is created in a thin-film structure by coating a substrate 14 in one pass with an ink having a major, fugitive component 13 and at least one minor, non-fugitive component 12 and treating, for example by pyrolysis, the ink to expel the major component 13 to leave the layer 15 of material. The non-fugitive component comprises one or more water soluble ceramic precursors such as water soluble compounds of a transition metal element, rare earth element or main group element or sols or water compatible organometallics and organic compounds containing non-metallic elements. The non-fugitive component may comprise colloidal ceramic nanoparticles having a size in the range 10 to 100 nanometres. The coating is performed by screen printing, offset lithography or pad printing.
