    摘要: A coated glass article includes a glass substrate. A coating is formed over the glass substrate. The coating includes a first inorganic metal oxide layer deposited over a major surface of the glass substrate. The first inorganic metal oxide layer has a refractive index of 1.6 or more. A second inorganic metal oxide layer is deposited over the first inorganic metal oxide layer. The second inorganic metal oxide layer has a refractive index which is less than the refractive index of the first inorganic metal oxide layer. A third inorganic metal oxide layer is deposited over the second inorganic metal oxide layer. The third inorganic metal oxide layer has a refractive index of 2.2 or more and the refractive index of the third inorganic metal oxide layer is greater than the refractive index of the second inorganic metal oxide layer. A fourth inorganic metal oxide layer is deposited over the third inorganic metal oxide layer. The fourth inorganic metal oxide layer has a refractive index which is less than the refractive index of the third inorganic metal oxide layer. The coated glass article exhibits a total visible light reflectance of less than 6.5%.
