The color film comprises a multi-layered optical film layer, wherein the multi-layered optical film layer is formed by alternately piling multiple fluorescent layers and multiple non-fluorescent layers; the reflective index of the non-fluorescent layer is (1.1)-(1.6); and the reflective index of the fluorescent layer is larger than that of the non-fluorescent layer. The color film provided by the invention has good visual sense of beauty in weak light or darkness, and the products are easy to find.

Description

A kind of color film
Technical field
The present invention relates to a kind of ornament materials, be specifically related to be used for a kind of color film of electronic product incrustation.
Background technology
Because the development of the progress of science and technology and society, electronic product is except the function of product own is strengthened, and the visual effect of its outward appearance also becomes one of index of the overall evaluation.Special visual effect is also decorated its case surface and is also had higher requirement.
At present, general adopt electroplate in case surface, multiple decorative means such as applying coatings.But it is more single, beautiful inadequately to electroplate color.The wearability and the poor stability that apply.So occurred at shell surface deposition multilayer optical film, utilize light refraction between plural layers different, thereby different angles present different colors with the light path of reflection and different angles, form and dazzle color effect.
Though the electronic product color of deposition optical thin film is beautiful abundant, under low light level situation, perhaps unglazed product at night will lose its gorgeous appearance, and the puzzlement that can not find product is often arranged.
Summary of the invention
Technical problem to be solved by this invention is: the color film in existing surface, can not satisfy under the low light level or the visual sense of beauty under unglazed, thereby the invention provides under a kind of low light level or the unglazed color film that still has the good visual aesthetic feeling down.
A kind of color film comprises the multilayer optical rete, and described multilayer optical rete is alternately piled up by some fluorescence coatings and some non-fluorescence coatings and forms; The refractive index of described non-fluorescence coating is 1.1～1.6; The refractive index of described fluorescence coating is greater than the refractive index of described non-fluorescence coating.
Color film provided by the invention, it still can have good visual sense of beauty under the low light level or in the dark, and is easy to search product.
The specific embodiment
A kind of color film comprises the multilayer optical rete, and described multilayer optical rete is alternately piled up by some fluorescence coatings and some non-fluorescence coatings and forms; The refractive index of described non-fluorescence coating is 1.1～1.6; The refractive index of described fluorescence coating is greater than the refractive index of described non-fluorescence coating.
Wherein, optical film is known in those skilled in the art.
Of the present invention alternately piling up is meant according to fluorescence coating/non-fluorescence coating/fluorescence coating/non-fluorescence coating ... mode pile up.
Non-fluorescence coating of the present invention is meant common optical film, promptly can not send the optical film of fluorescence.
The material of each non-fluorescence coating can be identical, also can be different.
Preferably, the material of non-fluorescence coating is selected from SiO, SiO 2And MgF 2In one or more.
Fluorescence coating of the present invention can send fluorescence under night or low light level situation.
The material of the preferred fluorescence coating of the present invention is selected from Y 2O 3: Eu, BaMg 2Al 16O 27: Eu, MgAl 11O 19: Ce, YBO 3: Tb, YBO 3: Eu, among the Gd one or more.
Wherein, Y 2O 3: Eu, BaMg 2Al 16O 27: Eu, MgAl 11O 19: Ce, YBO 3: Tb, YBO 3: Eu, Gd are fluorescent material known in those skilled in the art.Above-mentioned substance all can be commercially available or oneself preparation.
Fluorescent material generally is made of matrix and activator, and the present invention selects for use rare earth element as activator.
Preferably, the percentage composition of the rare earth element in the above-mentioned fluorescent material is 0.01～0.6wt%.
The material difference of preferred each fluorescence coating of the present invention, promptly some fluorescence coatings are made up of the fluorescence coating of different materials.Different fluorescence coatings can be launched the fluorescence of different wave length different colours, and reflection and refraction through between multilayer optical film can form more colorful visual effect.
Preferably, the refractive index of fluorescence coating is 1.8～3.
The preferred multilayer optical rete of the present invention is 4～15 layers, more preferably 5～11 layers.
The optical thickness of non-fluorescence coating and fluorescence coating is 1/2 λ in the optical film, and reflex is the most obvious during 1/2 λ.λ is that a certain visible light is at its propagation medium medium wavelength.
The geometric thickness of fluorescence coating is 100～195nm, and the geometric thickness of non-fluorescence coating is 140～260nm.
Preferably, multilayer optical rete of the present invention is SiO 2Layer and Y 2O 3: the multilayer optical rete that the Eu layer alternately piles up.
Multilayer optical rete of the present invention is owing to the refractive index of fluorescence coating and non-fluorescence coating is had any different, so constitute the alternately laminated multilayer film of high low-refraction with better optical effect.The material of fluorescence coating of the present invention, under high light effects such as sunshine, absorb luminous energy, luminous energy is stored, stop illumination penetrating the back or low light level situation under, the luminous energy that stores discharges in the mode of fluorescence lentamente, and,, still can see beautiful fluorescent effect at night or dark place through reflected refraction between high low-index layer.Special in the different fluorescent material of fluorescence coating employing, the effect that finally reaches is for to have under the optical condition, product surface presents bright and colourful color film, present the color film of fluorescence at night or dark place, can find easily used should the coloured silk film product, bring gorgeous color and convenient to life.
Color film provided by the present invention, it keeps adhesion, wearability and corrosion resistance better, and lucuriant in design, has fluorescent effect.
The preparation method of color film provided by the present invention is known in those skilled in the art.For example deposit etc.
Wherein, be deposited as physical vapor deposition (PVD) known in those skilled in the art, for example evaporation plating, sputter plating and ion plating etc.Plating is preferably evaporated in the present invention.
Wherein, the evaporation plating is to adopt box evaporation coating apparatus, sputter plating to adopt rf magnetron sputtering, ion plating to adopt the medium frequency magnetron sputtering ion plating equipment to realize plated film.These methods have been conventionally known to one of skill in the art, do not repeat them here.
In addition, preferably before substrate surface forms film, have the base material of greasy dirt to carry out ultrasonic wave for the surface and clean, described method for suppersonic cleaning also also is conventionally known to one of skill in the art, does not repeat them here.
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
