Problems solved by technology

[0006] However, although the single-layer vanadium dioxide film can adjust the infrared light transmittance, its visible light transmittance is low, and the infrared control ability (the difference between the infrared light transmittance between the semiconductor phase and the metal phase) is weak, which is smart and energy-saving. poor effect

Embodiment 1

[0036] First, deposit an aluminum-doped zinc oxide film 2 on a glass substrate 1 by sputtering: deposit a thickness h on a quartz glass substrate 1 by conventional radio frequency magnetron sputtering 2 Al-doped zinc oxide film 2 with a thickness of 75nm.

[0037] Then, sputter-deposit a vanadium dioxide film 3 on the formed aluminum-doped zinc oxide film 2: deposit a thickness h on the aluminum-doped zinc oxide film 2 by radio frequency magnetron sputtering 1 40nm vanadium dioxide thin film 3 . Thus obtain a light-transmitting structure with the vanadium dioxide-based composite film of the present invention (it is made of aluminum-doped zinc oxide film 2 and vanadium dioxide film 3), figure 1 (a) is a schematic diagram showing such a light-transmitting structure. Such as figure 1 As shown in (a), the light-transmitting structure includes a glass substrate 1 and a vanadium dioxide-based composite film, wherein the aluminum-doped zinc oxide film 2 is arranged on the glass su...

Embodiment 2

[0044] A light-transmitting structure with the vanadium dioxide-based composite thin film of the present invention was prepared in a manner similar to that of Example 1, except that the vanadium dioxide thin film was first arranged on a glass substrate, and the inorganic transparent thin film was arranged on the vanadium dioxide thin film On, and use the indium-doped tin oxide film as the inorganic transparent film. More specifically as follows:

[0045] First, on the quartz glass substrate 1, a vanadium dioxide film 3 is deposited by sputtering: on the quartz glass substrate 1, a thickness h is deposited by conventional radio frequency magnetron sputtering 1 42nm vanadium dioxide thin film 3 .

[0046] Then, on the vanadium dioxide film 3, deposit indium-doped tin oxide 2 by sputtering: on the formed vanadium dioxide film 3, deposit a thickness h by conventional radio frequency magnetron sputtering 2 Indium-doped tin oxide film 2 with a thickness of 205 nm. Thus obtain a l...

Embodiment 3

[0051] Prepare in a similar manner to Example 2 figure 1 (b) shows the light-transmitting structure with the vanadium dioxide-based composite film of the present invention, except that the indium-doped zinc oxide film is used as the inorganic transparent film.

[0052] First deposit a thickness h on a glass substrate 1 1 Be the vanadium dioxide film 3 of 50nm, then deposit thickness h on this vanadium dioxide film 2 215nm Indium-doped Zinc Oxide 2.

[0053] Similarly, for the light-transmitting structure obtained in Example 3, the present invention conducts electromagnetic field finite element simulation testing on its performance. Figure 4 shows the obtained by this Example 3 figure 1 (b) The electromagnetic field finite element simulation ultraviolet-visible-near-infrared transmission spectrum of the light-transmitting structure shown before and after the phase transition of the vanadium dioxide-based composite film, in which the vanadium dioxide-based composite film is ...

Abstract

The invention provides a transmissivity-adjustable vanadium-dioxide-based composite film, which comprises an inorganic transparent film and a vanadium-dioxide film, wherein the vanadium-dioxide film is arranged on the inorganic transparent film. The invention also relates to a transmissivity-adjustable transparent structure utilizing the vanadium-dioxide-based composite film and application of the transparent structure as intelligent energy-saving glass. By adopting the invention, the problems of low visible-light transmissivity, poor intelligent energy-saving effect caused by weak infrared adjusting and controlling forces and the like of existing vanadium-dioxide intelligent energy-saving glass are solved.

Description

technical field [0001] The invention relates to the field of energy-saving and environment-friendly materials, in particular to an environment-friendly and energy-saving inorganic material composite film and its application. Background technique [0002] my country is a country with energy shortage. The utilization efficiency of coal-based non-renewable resources is low, the degree of development and utilization of renewable resources is low, the environmental pollution is serious, the supply of high-quality energy is insufficient, and the form is increasingly tense. Therefore, energy conservation and environmental protection have become Times theme. Among all kinds of energy consumption, my country's building energy consumption has accounted for more than one-third of the total energy consumption of the society, of which the energy consumption of heating and air conditioning accounts for about 55% of the total energy consumption of buildings, and the energy consumption per u...
