transparent substrate with antireflection coating low emissivity or solar protection.

摘要

Transparent substrate includes on at least one of its faces an antireflection coating made of a stack of thin layers indices alternately high and low refractive-based dielectric material, wherein at least one of the thin layers of high index said antireflection coating comprises titanium oxide deposited by sputtering which is chemically modified by incorporation of nitrogen so as to reduce its refractive index to a value of at most 2, 40, in particular 2, 38 and preferably to values between 2 25 and 2, 38 of a wavelength of 580 nm.
