Abstract
A coated glass element includes: a glass surface and a coating that coats at least part of the glass surface. The coating has at least one layer. The at least one layer of the coating fulfills the following parameter: [Al+]80/[Al+]20≥1.8. [Al+]20 are counts of [Al+] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface and [Al+]80 are counts of [Al+] ions, measured by a TOF-SIMS, at 80% of a time a sputter gun beam needs to reach the glass surface.

A coated glass element, comprising:
- a glass surface;
- and
- a coating that coats at least part of the glass surface, the coating comprising at least one layer, the at least one layer of the coating fulfills the following parameter:
- [Al+]80/[Al+]20≥1.8;
- wherein [Al+]20 are counts of [Al+] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface;
- and
- wherein [Al+]80 are counts of [Al+] ions, measured by a TOF-SIMS, at 80% of the time the sputter gun beam needs to reach the glass surface, wherein the coating is formed from a precursor P1 that comprises at least one the following:
- hexamethyldisiloxane (HMDSO), hexamethyldisilazane (HMDS), tetramethylsilane (TMS), trimethylborazole (TMB), tri(dimethylaminosilyl)-amino-di(dimethylamino)borane (TDADB), tris(trimethylsilyl)borate (TMSB), hexamethylcyclotrisiloxane (HMCTSO), octamethylcyclotetrasiloxane (OMCTS), decamethylcyclopentasiloxane (DMCPS), dodecamethylcyclohexasiloxane (DMCHS) diacetoxy-di-t-butoxysilane (DADBS), tetraethoxysilane (TEOS), tris(trimethylsilyloxy)vinylsilane (TTMSVS), or vinyltriethoxysilane (VTES).
A coated glass element, comprising:
- a glass surface;
- and
- a coating that coats at least part of the glass surface, the coating comprising at least one layer, the at least one layer of the coating fulfills the following parameter:
- [Al+]80/[Al+]20≥1.8;
- wherein [Al+]20 are counts of [Al+] ions, measured by a time-of-flight secondary ion mass spectrometry (TOF-SIMS), at 20% of a time a sputter gun beam needs to reach the glass surface;
- and
- wherein [Al+]90 are counts of [Al+] ions, measured by a TOF-SIMS, at 90% of the time the sputter gun beam needs to reach the glass surface, wherein the coating is formed from a precursor P1 that comprises at least one the following:
- hexamethyldisiloxane (HMDSO), hexamethyldisilazane (HMDS), tetramethylsilane (TMS), trimethylborazole (TMB) tri(dimethylaminosilyl)-amino-di(dimethylamino)borane (TDADB), tris(trimethylsilyl) borate TMSB), hexamethylcyclotrisiloxane (HMCTSO), octamethylcyclotetrasiloxane (OMCTS), decamethylcyclopentasiloxane (DMCPS), dodecamethylcyclohexasiloxane (DMCHS) diacetoxy-di-t-butoxysilane (DADBS), tetraethoxysilane (TEOS), tris(trimethylsilyloxy)vinylsilane (TTMSVS), or vinyltriethoxysilane (VTES).
