When light irradiation, invisible two-dimensional codes layer 2 will become blue, and the background background color layer 1 of two dimensional code can issue red fluorescence, show fresh
Gorgeous pattern in 2 D code, and after stopping ultraviolet light irradiation, blue two dimensional code will continue to keep, and background background color layer 1 is not
Red fluorescence is issued again, finally two-dimension code area is heated, two dimensional code can fade again, become colorless, and be hidden in printing
In product, multi-anti-counterfeit effect is played.
The specific working principle is as follows: the principle of invisible two-dimensional codes colour developing is the WO under ultraviolet lighting3Electronics is swashed in valence band
It is dealt into conduction band, hole is left in valence band, generates electron-hole pair, light induced electron times W6+Capture generates W5+, while photoproduction is empty
Cave and WO3The reduzate reaction of powder surface absorption, releases proton H+, the proton of releasing is internally spread along surface, through inside
Transmission and WO between different lattices3It is compounded to form tungsten bronze HxWO3, HxWO3In W5+The transition of electronic service guide band makes powder in valence band
Blue is presented.
The principle that two dimensional code fades is: two dimensional code is heated in air, so that HxWO3It is oxidized to WO again3, blue takes off,
Restore primary colors.
The principle that background background color layer 1 becomes red under ultraviolet lighting is: Y2O3: Eu fluorescent material can absorb certain form
Energy, and excitation photon is released the energy of absorption in the form of low visible light, to generate red fluorescence phenomenon.
The present invention has triple antifalse effects, includes invisible two-dimensional codes, and change colour two dimensional code and fluorescence background, in particular to the
Anti-fake one weight is so that invisible two-dimensional codes is developed the color by ultraviolet lighting, then carry out mobile phone scanning, checks the true and false, the second weight into official website
It is after two dimensional code colour developing, needing to heat could fade, and user can carry out second by way of heating to two dimensional code
Anti-counterfeit recognition again illustrates to belong to counterfeit and shoddy goods as colour-fast；Third is that two dimensional code background can be sent out under ultraviolet lighting again
Red visible light out, on the one hand which can form a sharp contrast with the two dimensional code of blue, so that two dimensional code
It can quickly be scanned, the anti-fake knowledge of third weight on the other hand can also be carried out by the color change of the background background color layer 1
Not, also explanation belongs to counterfeit and shoddy goods if background background color layer 1 is non-discolouring or non-red.Pass through triple anti-counterfeiting technology phases
