Abstract

A process includes the formation of a colored glass layer on a glass substrate by flame pyrolysis of a solution including at least one precursor of a cobalt, iron, manganese, chromium, silver, copper, gold or selenium oxide, alone or as a mixture of several of them. Moreover, a glass substrate is coated with a layer of colored glass obtained by such a process.

Claims

1. A process comprising forming a colored glass layer on a glass substrate by flame pyrolysis of a solution comprising at least one precursor of a cobalt, iron, manganese, chromium, silver, copper, gold or selenium oxide, alone or as a mixture of several of them.

2. The process as claimed in claim 1, wherein precursors in solution are introduced into and then decomposed in a burner to give glass nanoparticles which are deposited on said glass substrate at a temperature between ambient temperature and 600°

C.

3. The process as claimed in claim 2, wherein said precursors consist of organometallic compounds and/or salts.

4. The process as claimed in claim 2, wherein said precursors are soluble in alcoholic solution.

5. The process as claimed in claim 1, wherein a distance from the burner to the glass substrate is at most equal to 10 mm.

6. A glass substrate coated with a layer of colored glass obtained by a process as claimed in claim 1, wherein a thickness of the layer of colored glass is between 50 et 10 000 nm.
