This relates to a UV light absorbing filter that is controlled accordingly. UV light absorber The filter is manufactured from a two-component or three-component metal oxide thin film. PREVIOUS TECHNIQUE UV absorbing materials absorb harmful ultraviolet rays, reducing the amount of UV light present. They convert energy into energy that carries harmless vibrations, thus damaging the polymer. They protect against radiation. UV absorbing materials do not degrade quickly. However, it converts UV energy into harmless heat energy levels that are distributed throughout the polymer matrix. They transform it. In the known technique, the UV absorber material is made from plastic material. It is manufactured. Its UV absorption property is 15, depending on the production conditions. It is not being changed. However, it is controlled depending on the production conditions and Thin, UV-absorbing materials are needed. LIST OF FIGURES Figure 1.

UV absorber filter (4); zinc oxide It consists of zinc oxide (ZnO), titanium oxide (TiO2), and tin oxide (SnO2) materials. UV The absorber filter (4) has the chemical formula kZnOxlSnO2ymTiO21-y. In the formula, x and 2 y represents atomic ratios. x values ​​are: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 or at least 1.0. It is one of the following y values: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 or 1.0. In the formula, k, l, and m are molar ratios. The k values ​​are: 0.1, 0.2, 0.3, 0.4, or 0.5. At least one of these is true. l values: 0.6, 0.7, 0.8, 0.9 or 1.0. At least one of these. m values: 1.0, 1.5 or 2.0. It is one of them. 5 ZnO, SnO2 and TiO2 metal oxide materials forming the nano absorber film (3), It has the structure of nanorods, absorbent nanoballs, nanowires, nanoflowers, and nanodonuts. The film prepared with nanomaterials is defined as nano absorbent film (3) and The filter prepared with this is defined as a nano UV absorber filter (4). Nanostructure, Checks the absorption property of the nano absorber film (3). Nano absorber film 10 (3) absorption property, nanorod, sorptor nanotop, nanowire, nanoflower, nanobagel These structures control the absorption limit of the nano absorber film (3). It changes the absorption wavelength region and the absorption wavelength region. UV absorbing filter (4); optical glass, indium tin oxide and sol gel method. Fluorine tin oxide is prepared on glass substrates (1). The resistance of the glass substrates (1) is 1-30 15 It is between ohm / square. Absorption property of nano absorber film (3) with resistance It varies. Resistance is the voltage value per unit current. UV absorber filter (4) 1-30 The substrates (1) with ohm / square resistance are coated by the sol gel method. Nano conductivity of the absorber film (3) absorbing property of the UV absorber filter (4) It checks. Electric conductivity is the number of carrier charges per unit electric field. It is defined as S / cm, and its unit is S / cm. S stands for Siemens and cm stands for centimeter. The conductivity of the UV absorber filter (4) is controlled by the molar values ​​of k, l and m. These values ​​change the resistance, i.e., the electrical conductivity, of the nano absorber film (3). As a result, the optical absorption of the material changes. Absorption property It is determined by the absorption coefficient. The absorption contribution is the ratio of unit light per unit length to 25. It is the degree of absorption per head. In our invention, the absorption of the nano absorber film (3) is controlled by the resistance of the film. The resistance of the nano absorber film (3) is at least 1 ohm / square, and its conductivity is at least 1x10-4 It is S / cm. In our invention; the absorption of the nano absorber film (3) is controlled by its thickness 30 The thickness of the nano absorber film (3) is at least 20 nm. The molar values ​​of k, l, m are UV Checks the thickness and optical transmittance of the absorber filter (4). Optical transmittance It is the light transmittance property of the filter. The optical transmittance value is higher than that of a UV absorbing filter (4) It is the ratio of the passing light intensity to the incident light intensity on the surface of the UV absorber filter (4). 3 Therefore, the absorption of the UV absorber filter (4) is given by the molar values ​​k, l and m. Conductivity values, thickness values, and optical transmittance values ​​are used for control. UV The optical transmittance of the absorbing filter (4) is also controlled by the molar values ​​k, l and m. The m values ​​control the UV wavelength range. The x, y, and z values, on the other hand, determine the filter's range. It determines the absorption limit and monitors the absorption value. 5 The roughness of the UV absorber filter (4) is controlled by the spin coating speed. Spin Coating speed is the speed of the spin coating machine, and its unit is RPM. RPM is per minute. Roughness is the rotation speed. Roughness reflects light off the surface of the UV absorber filter (4). and this feature controls the absorption value of the UV absorber filter (4). The UV absorber filter (4), produced in the form of a thin nano absorber film (3), UV 10 The absorption property is controlled at the nanoscale. Nanoabsorbents are produced at the nanoscale. The size of the particles from which the film (3) is formed is defined as the nanosize 100 These are values ​​smaller than nanometers (nm). The nanosize of the nano absorber film (3) is at least It should be 8 nm (at nanoscales of 8 nm, 10 nm, 15 nm and 20 nm). Nano absorber The absorption property of the film (3) varies depending on the nanoscale and this quantum confinement 15 It is called the effect of the nano absorber film (3) and the UV absorber filter (4). The absorption property is controlled by the quantum confinement effect. 25
