Description
Technical field
The utility model belongs to glass technology field, particularly relates to a kind of energy-efficient temperature photo chromic glass.
Background technology
Along with environmental protection, energy-conservationly day by day to come into one's own, the Appropriate application of the energy, the Study and Development of energy-conserving product obtain very large progress.Under this background, the eighties, first C.M.Lampert, C.G.Granqvist etc. proposed to be applied to by electrochromic material in the energy-conservation lighting systems such as building, automobile, aircraft in earlier stage, formed " smart window " (Smartwindow) that dynamic regulates solar radiant energy transmitance.In recent years, the Study and appliance of smart window is the focus of research always.
The Discoloration mechanism of smart window can be divided into electrochromism (electricity is quick), temperature induced color changing (temperature-sensitive), gas-discoloration (air-sensitive) and photochromic (photosensitive) etc.Smart window based on these Discoloration mechanisms all can realize sunshine adjustment in various degree.
For temperature induced color changing smart window, existing temperature induced color changing smart window normally obtains by depositing one deck temperature induced color changing layer at glass baseplate surface.Vanadium dioxide (VO
2) be a kind of typical thermochromic material, its phase transition temperature is 68 DEG C.Lower than this temperature, it is characteristic of semiconductor, medium transparent; During higher than 68 DEG C, in metallic character, to infrared high reverse--bias.But, because its phase transition temperature is far away higher than room temperature, at room temperature, with VO
2the temperature induced color changing smart window formed as thermochromic material cannot play its colour change function at all, also just cannot realize the technique effect sun being closed to adjustment in various degree.
In order to solve VO
2the phase transition temperature of thin layer itself is higher, cannot realize the problem of room temperature lower the look that changes, and Many researchers adopts at VO
2mix metallic element in thin layer as W, Cr, Mo, Co, Nb, Mn, Fe, Ti, Ag etc. or mix nonmetalloid as F, N, H etc. or add other compound and form temperature induced color changing layer, the phase transition temperature of this temperature induced color changing layer is dropped near room temperature.But, this mode of dealing with problems, except there is the problem that how is dispersed in by mixed element in target in manufacturing process except, also there is the problem that the variable color uniformity of the temperature induced color changing layer caused due to the sputtering rate difference when sputter between different materials is bad.
Summary of the invention
The utility model aim to provide a kind of under normal temperature condition with the energy-efficient temperature induced color changing glass that sunlight strength is with an automatic light meter.
A kind of energy-efficient temperature induced color changing glass, comprise the first glass substrate, the upper surface of the first glass substrate is provided with three-dimensional protruding lines, three-dimensional protruding lines is the class convex lens shape gathered to center gradually from the bottom to top, then deposits the first ion barrier and vanadium dioxide film successively at the upper surface of the first glass substrate.
