Region cannot can generate transmitting light in storage energy under ultraviolet light irradiation, but under ultraviolet light or Infrared irradiation；
Anti-counterfeiting information can be written in second area by ultraviolet light, i.e. second area is the safety with read-write function
Information image-text area can get up the energy stores of ultraviolet light under ultraviolet light irradiation, realize information write-in, and further
Using infrared ray excited, it can release the stored energy, to generate transmitting light, realize the reading of information.But if
Anti-counterfeiting information is not written by ultraviolet light in advance, then cannot be shone by infrared excitation.
In this way, the first area and second area in safety design have the above-mentioned different characteristics of luminescence, therefore can be mutual
The coding letter of the safety design can be accordingly obtained by carrying out Infrared irradiation and ultraviolet light to safety design for control
Breath, and then by the situation of change of encoded information, determines the true and false of security article, thus the security article have concealment height and
Feature easy to detect.
Specifically, above-mentioned encoded information, can usually be indicated with " 0 " and " 1 ", shine (being able to detect that luminous signal) note
For " 1 ", luminous (luminous signal is not detected) is denoted as " 0 ".If can be shone by infrared ray excited than first area, simultaneously
Anti-counterfeiting information is not written by ultraviolet light in advance in second area, then under Infrared irradiation, the encoded information of first area be " 1 " and
The encoded information of second area is " 0 ", and the encoded information of safety design is " 10 ".
It is appreciated that above-mentioned ultraviolet light should have certain luminous intensity, with can be when irradiating second area, ultraviolet light
At least partly energy can be stored by second area, and it is subsequent using it is infrared ray excited when, second area can be swashed
Hair shines.Therefore, ultraviolet light contained in common daylight is obviously unsatisfactory for the requirement of above-mentioned ultraviolet light.Correspondingly, common day
Infrared light contained in light is not able to satisfy the requirement of above-mentioned infrared light similarly, and this eliminates security articles in common daylight
