Abstract
This invention is a product comprising a transparent substrate of the glass substrate type (1), coated with at least one thin film (4) based upon an oxide comprising silicon, aluminum and at least one third element M facilitating the formation of a homogeneous mixed oxide structure of silicon and aluminum. The invention also concerns a method of manufacturing coated glass, especially by a gas phase pyrolysis technique, and its applications.
Claims32
A product comprising
- (a) a transparent substrate, and
- (b) a homogeneous thin film, on said substrate;
- wherein said homogeneous thin film is formed by pyrolysis and comprises a mixed oxide of silicon and aluminum, and an additive amount of an element M, which is a halogen.
A method for preparing a product comprising:
- pyrolizing in the gas phase at least a first and a second precursor, thereby depositing a homogeneous thin film on a transparent substrate,
- wherein said first precursor comprises silicon, said second precursor comprises aluminum, and wherein said first or second precursor further comprises a halogen, and said homogeneous thin film comprises a mixed oxide of silicon and aluminum and an additive amount of an element M, which is a halogen.
A pane comprising:
- a homogeneous thin film, on a transparent substrate;
- wherein said homogeneous thin film is formed by pyrolysis and comprises a mixed oxide of silicon and aluminum, and an additive amount of an element M, which is a halogen.
