<p>Transparent (especially glass) substrate (1) has, on one or both faces, a thin film coating (6) including a film (A) containing an aluminium fluoride or oxyfluoride of formula (I): AlxOyFz (I), where y≥0. Also claimed is monolithic glazing, in laminated form or in multiple glazing form with interposed gas, which incorporates the above substrate. Preferably, film (A) has a refractive index of less than 1.63 (preferably 1.60-1.32, especially 1.45-1.35), has a F/Al atomic ratio of 0.10-3 (preferably 0.10-2.50, especially 0.16-2.45) and has an O/F atomic ratio of 0-10 (preferably 0.1-10, especially 0.15-9). The film (A) may also contain one or more of SiO2, SnO2 and NiO.</p> |
