A process for depositing an inorganic material on a substrate, the process comprising, providing a substrate having a surface, providing a precursor mixture comprising a metal sulfonate, and delivering the precursor mixture to the surface of the substrate, wherein the surface of the substrate is at a substrate temperature of above 450? C. and is sufficient to effect decomposition of the metal sulfonate. The inorganic material may include a metal or a metal oxide. The preferred metal sulfonate is metal triflate.

Provided is a method of manufacturing a tempered glass sheet that has been tempered by an ion exchange process, the method including: a film forming step of covering a surface of an original glass sheet with an ion permeation suppressing film configured to suppress permeation of an alkali metal ion, to thereby provide a glass sheet with a film; a processing step of subjecting, after the film forming step, the glass sheet with a film to at least any one of cutting processing, end-surface processing, and hole-opening processing, to thereby provide a glass sheet to be tempered including an exposed portion free from being covered with the ion permeation suppressing film; and a tempering step of chemically tempering, after the processing step, the glass sheet to be tempered by the ion exchange process to provide a tempered glass sheet.

In one embodiment, a chromatic device includes an active layer and an electrolyte layer in contact with the active layer, wherein the active layer has an opaque color that blocks light but changes to a translucent color that transmits light when a metal object is placed in electrical contact with the active layer in the presence of the electrolyte layer.
