SiOxNyFor SiO2And Si3N4Mesophase.
Wherein in an embodiment, the thickness of described first high refractive index layer is
Wherein in an embodiment, the thickness of described second high refractive index layer is
Wherein in an embodiment, the thickness of described first low-index layer is
Wherein in an embodiment, the thickness of described second low-index layer is
Wherein in an embodiment, the thickness of described AZO film layer is
Above-mentioned electro-conductive glass, owing to being provided with the first high refractive index layer, first refractive index graded bedding, the first low folding
Penetrate rate layer, the second high refractive index layer, the second graded-index layer and the second low-index layer and replace traditional SiO2
Layer, the film layer structure that transmitance height combines can not only realize disappearing the effect of shadow, can considerably increase AZO simultaneously
The transmitance of film layer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the electro-conductive glass of present embodiment;
In figure, 1-glass substrate, 2-the first high refractive index layer, 3-first refractive index graded bedding, the low folding of 4-first
Penetrate rate layer, 5-the second high refractive index layer, 6-the second graded-index layer, 7-the second low-index layer, 8-AZO
Film layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this utility model
Advantage and feature can be easier to be readily appreciated by one skilled in the art, thus to protection domain of the present utility model
Make apparent clear and definite defining.
Referring to Fig. 1, a kind of electro-conductive glass, including glass substrate the 1, first high refractive index layer stacked gradually
2, first refractive index graded bedding the 3, first low-index layer the 4, second high refractive index layer the 5, second refractive index is gradually
Change layer the 6, second low-index layer 7, AZO film layer 8;
Glass substrate 1 can select float glass or the glass of other this areas routine.
The material of the first high refractive index layer 2 is TiO2、ZrO2Or Si3N4。TiO2Refractive index be 2.3, ZrO2
Refractive index be 2.17, Si3N4Refractive index be 2.0.The thickness of the first high refractive index layer is
The material of the first low-index layer 4 is SiO2Or MgF2。SiO2Refractive index be 1.48, MgF2Refraction
Rate is 1.38.The thickness of the first low-index layer 4 is
The material of the second high refractive index layer 5 is TiO2、ZrO2Or Si3N4.The thickness of the second high refractive index layer 5
Degree is
The material of the second low-index layer 6 is SiO2Or MgF2.The thickness of the second low-index layer 6 is
The material of first refractive index graded bedding the 4, second graded-index layer 7 is all SiOxNy, SiOxNyFor
SiO2And Si3N4Mesophase, its optically and electrically performance fall between, thus can by change chemistry
Composition, can make its variations in refractive index scope is 1.47~2.3, therefore can be by SiOxNyFilm layer joins high folding
Penetrate between rate layer and low-index layer, and by its chemical composition of continuous control process parameter change so that it is
Become the film material of one layer of gradually changed refractive index.
The thickness of AZO film layer 8 is
Above-mentioned electro-conductive glass, owing to being provided with the first high refractive index layer, first refractive index graded bedding, the first low folding
Penetrate rate layer, the second high refractive index layer, the second graded-index layer and the second low-index layer and replace traditional SiO2
Layer, the film layer structure that transmitance height combines can not only realize disappearing the effect of shadow, can considerably increase AZO simultaneously
The transmitance of film layer.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that,
For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to
Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model
The protection domain of patent should be as the criterion with claims.
