Abstract
The invention discloses the anti-fake material preparation methods that a kind of multiple optics signal by Spin transition regulation and control responds, and by the way that spin conversion materials and luminescent material are obtained by mixing composite material, feature is shown as the present invention：Exportable four kinds of color signals for having notable difference after input temp, ultraviolet light, visible light signal.The composite material realizes luminous regulating and controlling effect by Spin transition the antiforge function that multiple optics signal responds, and synthetic method is simple, is easy to practical operation, and simple and convenient, applied to anti-fake middle concealment higher, uniqueness is stronger, and antifalse effect is more preferable.
Description
Technical field
The present invention relates to a kind of preparation methods of anti-fake material, refer in particular to a kind of utilization spin conversion materials and luminescent material
Synergistic effect input temp, ultraviolet, exportable multiple optics signal after visible light signal anti-fake material preparation method.
Background technology
With the deep development of market economy, the material life of people has obtained greatly enriching, but when people are enjoying
Also a large amount of counterfeit and shoddy goods that market is crowded with while by life are puzzled.Especially by with various new and high technology systems
Fakement, anti-counterfeiting mark and the anticounterfeit package of work are easy to original anti-counterfeit measures ineffective.In order to protect consumer
Rights and interests and businessman economic interests, various new, efficient anti-counterfeiting technologies are researched and developed, uniqueness is strong, good concealment
Characteristic chemical material be applied to anti-counterfeit field and become the direction that world anti-counterfeiting technology develops.It is existing at present to utilize organic fluorescence
Dye molecule prepares the anti-fake material of multiple response, but there has been no the synergistic effects using Spin transition and luminescent material to prepare
The report of anti-fake material.
Anti-fake material in the present invention is by Spin transition nano-particle [Fe (4-NH2trz)3](ClO4)2（4-NH2Trz is
4- amino -1,2,4- triazoles）With the coordination polymer [Tb (H to shine at 544 nm4btca).3H2O]n （H4Btca for [1,
1'- biphenyl] -2,3,3', 5'- tetrabasic carboxylic acids）It is combined.Since Fe (II) Spin transition compound is in low spin state（low
spin）When have strong absorption to the light near 550 nm, in high spin state（high spin）When to the light absorption near 550 nm then
It completely disappears.According to this principle, Spin transition particle can be combined with the material to shine near 550 nm, thus
It can be spinned-be shone and be associated and with the composite material of multiple optics signal response.At normal temperatures, Spin transition nanoparticle
For son in high spin state, which is white in solar radiation, and has bright green fluorescence in the UV lamp；Compared with
Under low temperature（Less than 210K）, Spin transition nano-particle is in the low spin state composite material and becomes purple in solar radiation
Color, in ultra violet lamp to be blackish green.The method for synthesizing composite material is simple and convenient to operate, concealment is strong, is not easy by mould
It is imitative, and responded with multiple optics signal, its this characteristic makes it have huge application prospect in terms of anti-fake discrimination.
The content of the invention
It obtains having the object of the present invention is to provide a kind of synergistic effect using spin conversion materials and luminescent material more
The anti-fake material of weight optical signalling response.
To achieve the above object, the present invention takes that the technical scheme comprises the following steps：
By thermally sensitive Spin transition nano-particle [Fe (4-NH2trz)3](ClO4)2With the rare earth to shine at 544 nm
Coordination polymer [Tb (H4btca).3H2O]nIt is mixed and can obtain composite material, optimum mixture ratio example is 6:1.
The feature of obtained composite material is：At normal temperatures, [Fe (4-NH2trz)3](ClO4)2In high spin state,
Composite material is white during solar radiation, and then there is strong green fluorescence in when ultra violet lamp.At low temperature（< 210K）, [Fe (4-
NH2trz)3](ClO4)2In low spin state, composite material is purple during solar radiation, and green fluorescence disappears during ultra violet lamp
And become blackish green.It can be seen that temperature, ultraviolet and visible ray, when multiple signals input, exportable four kinds of composite material is not
With the signal of color, phenomenon is as shown in Figure 1, it will be apparent that, naked eyes are distinguishable.
The present invention has the following advantages compared with existing process technology：It is simple for process；It is easy to operate；Spin regulation and control shine；It is more
Weight signal response；It is not easy to be imitated.
