Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
Fig. 1 is a schematic structural view of a neutral spectroscopic film glass with a reflection of 30%.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a neutral spectroscopic film glass with a reflection of 30% comprises an ultra-white glass substrate 1, a first niobium pentoxide film 2 coated on the ultra-white glass substrate, a silicon dioxide film 3 coated on the upper surface of the first niobium pentoxide film 2, and a second niobium pentoxide film 4 coated on the upper surface of the silicon dioxide film 3.
Wherein the thickness of the silicon dioxide film is 5 times of that of the first niobium pentoxide film, and the thickness of the second niobium pentoxide layer is 7 times of that of the first niobium pentoxide film.
Because the niobium pentoxide contained in the first niobium pentoxide film 2 and the second niobium pentoxide film 4 is a high refractive index material, and the silicon dioxide contained in the silicon dioxide film 3 is a low refractive index material, the three materials are mutually matched to form the reflecting film layer, and the film layer structure brings the neutral color effect of light splitting with the reflection of 30%, the transmission of 70% and the CRI index of 99%.
The neutral light splitting film glass can reflect light by 30 percent and transmit light by 70 percent, and the CRI index is 99 percent.
In one example, the first niobium pentoxide film had a thickness of 9.8 nm, the silicon dioxide film had a thickness of 50 nm, and the second niobium pentoxide film had a thickness of 71 nm.
A large number of experiments show that the CRI index of the reflecting film layer formed by matching the first niobium pentoxide film 2, the silicon dioxide film 3 and the second niobium pentoxide 4 under the thickness is highest, and the shadow eliminating layer formed by matching the first niobium pentoxide film 2, the silicon dioxide film 3 and the second niobium pentoxide layer 4 under the thickness can realize that a neutral light splitting film reflecting 30% can be formed on the ultra-white glass substrate.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
