Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a photochromic pigment with high color saturation provided by the present application, wherein the photochromic pigment with high color saturation comprises: a reflective layer 11 and a dielectric stack 12, wherein the dielectric stack 12 is disposed on at least one major surface of the reflective layer 11.
In the embodiment shown in fig. 1, the dielectric stack 12 is provided on the main surface on the side of the reflective layer 11. The dielectric stack 12 includes a first dielectric layer 121, an absorption layer 122, a second dielectric layer 123 and a plurality of metal nanoparticles 124, which are sequentially stacked. The first dielectric layer 121 is located between the reflective layer 11 and the absorption layer 122. The photochromic pigment has simple integral structure and convenient manufacture.
Gaps are formed between the metal nanoparticles 124, for example, the metal nanoparticles 124 are spaced apart from each other to expose the bottom film layer. The refractive index of the second dielectric layer 123 is greater than 1.65, for example, the refractive index of the material of the second dielectric layer 123 is 1.7, 1.8, or 1.9, and the like, that is, the material of the second dielectric layer 123 may be a material with a high refractive index.
The photochromic pigment provided by the application has the optically variable effect of changing color along with the angle under natural light and has different color changes under strong light irradiation by utilizing the interference effect of the film layer and the enhancement effect of the metal nano particles 124 on scattered light, so that the photochromic pigment has double anti-counterfeiting effects, better anti-counterfeiting effect and higher counterfeiting difficulty; in addition, the photochromic pigment has a simple overall structure and good monochromaticity. The photochromic pigment with high color saturation can be prepared into pigments and films, and has a wide application range.
It should be noted that the photochromic pigment of the present application can realize color change under high intensity visible light, such as mobile phone light, which is mainly characterized in that the metal nanoparticles 124 have enhanced light scattering to the selective wavelength of the incident light under the action of high light, and the phenomenon is caused by a localized surface plasmon resonance phenomenon. The localized surface plasmon resonance is an optical phenomenon in which the metal nanoparticles 124 with a size smaller than the wavelength of light absorb light waves, and means that under the irradiation of incident light, electron clouds in the metal nanoparticles 124 are redistributed to generate polarization, thereby generating positive and negative electron clouds. When the polarization direction of incident light is parallel to the connection direction of the two metal nanoparticles 124, the positive and negative electronic cloud terminals are respectively distributed at the left and right ends of the metal nanoparticles 124, and the heterogeneous charges enriched on the particle surfaces at the two sides of the gap generate a strong electromagnetic field, which is called as a "hot spot". The 'hot spot' area has strong light scattering enhancement effect on incident light, and a scattering spectrum has certain peaks and troughs, so that the color of the material observed by naked eyes is changed under high-intensity illumination. Since the light scattered by the material is primarily visible to the naked eye under high light, the color change can be seen without looking for a specific viewing angle.
In other embodiments, as shown in fig. 2, fig. 2 is a schematic structural diagram of another embodiment of the photochromic pigment with high color saturation provided in the present application, in this embodiment, the photochromic pigment is disposed in a symmetrical structure, for example, the dielectric stack 12 may be symmetrically disposed on two main surfaces of the reflective layer 11 opposite to each other. The effects of the above embodiments can be achieved with both opposing sides of the photochromic pigment.
Alternatively, the thickness of the reflective layer 11 is in the range of 5-200nm, for example, the thickness of the reflective layer 11 may be 5nm, 10nm, 20nm, 30nm, 40nm, 50nm, 80nm, 90nm, 100nm, 110nm, 140nm, 150nm, or the like.
The material of the reflective layer 11 may include one of aluminum, silver, copper, gold, platinum, tin, titanium, palladium, nickel, cobalt, rhodium, niobium, chromium, or an alloy of at least two of these materials.
The absorber layer 122 has a thickness in the range of 3-30 nm. For example, the thickness of the absorption layer 122 may be 3nm, 5nm, 10nm, 15nm, 20nm, 25nm, or 30nm, etc. The material of the absorption layer 122 may include: one or an alloy of at least two of titanium, aluminum, chromium, nickel, palladium, titanium, vanadium, cobalt, iron, carbon, tin, tungsten, molybdenum, rhodium, niobium.
Optionally, the refractive index of the material of the first dielectric layer 121 is less than or equal to 1.65, for example, the refractive index of the material of the first dielectric layer 121 is 1.1, 1.3, 1.6, 1.65, and the like. The refractive index of the material of the first dielectric layer 121 is smaller than that of the material of the second dielectric layer 123, and in this way, the color change effect of the photochromic pigment can be improved, so that the pigment has better monochromaticity.
When the first dielectric layer 121 is a low refractive index layer, the materials of the first dielectric layer 121 include: silicon dioxide, aluminum oxide, magnesium fluoride, aluminum fluoride, cerium fluoride, lanthanum fluoride, neodymium fluoride, samarium fluoride, barium fluoride, calcium fluoride, lithium fluoride polystyrene, polyethylene, polymethyl methacrylate, polyamideimide, polyperfluoroethylpropylene, tetrafluoroethylene, chlorotrifluoroethylene, cellulose propionate, cellulose acetate butyrate, methylpentene polymer, homopolyformaldehyde, acrylic resin, cellulose nitrate, ethyl cellulose, polypropylene, polysulfone, polyethersulfone, mica, a heteroisomorphous polymer, polybutene, an ionomer, an acrylic copolymer, a thermoplastic, styrene butadiene, polyvinyl chloride, urea formaldehyde, styrene acrylonitrile, polycarbonate.
In other embodiments, the refractive index of the first medium layer 121 may be greater than 1.65, which also enables the photochromic pigment to have a light-variable effect. When the first dielectric layer 121 is also a high refractive index layer, the material of the first dielectric layer 121 may be the same as that of the second dielectric layer 123, and in other embodiments, the material of the first dielectric layer 121 may also be different from that of the second dielectric layer 123.
The physical thickness of the first dielectric layer 121 is 10-800nm, for example, the physical thickness of the first dielectric layer 121 may be 10nm, 50nm, 100nm, 200nm, 250nm, 300nm, 400nm, 500nm, 550nm, 600nm, 700nm, 800nm, or the like.

Alternatively, the second dielectric layer 123 may have a single-layer structure, for example, the second dielectric layer 123 may have only one high refractive index layer structure; in other embodiments, the second medium layer 123 may include at least one high refractive index layer and at least one low refractive index layer, wherein the high refractive index layer and the low refractive index layer are alternately arranged in sequence, that is, the second medium layer 123 may be formed by alternately stacking a plurality of high refractive index layers and low refractive index layers to achieve a specific refractive index.
Alternatively, the first dielectric layer 121 may also be a single-layer structure, for example, the first dielectric layer 121 may be only a low refractive index layer structure; in other embodiments, the first medium layer 121 may include at least one high refractive index layer and at least one low refractive index layer, wherein the high refractive index layer and the low refractive index layer are alternately disposed in sequence, i.e., the first medium layer 121 may be disposed by alternately stacking a plurality of high refractive index layers and low refractive index layers to achieve a certain refractive index.
Also, the material of the metal nanoparticles 124 is at least one or an alloy of at least two of aluminum, silver, gold, copper, platinum, ruthenium, palladium, rhodium, cobalt, iron, nickel, lead, osmium, and iridium.

The size of the metal nanoparticles 124 is 5nm to 1 μm, such as 5nm, 10nm, 50nm, 100nm, 500nm, or 1 μm, and the like.
