Embodiment 1
[0035] Embodiment one: see figure 1 , the mobile phone 1 is connected to the accessory device 2 through the connection terminal 3 of the accessory device; there are two special light sources 4 on the accessory device 2 . One of the special light sources 4 is (200nm-300nm) short-wave ultraviolet light source; the other is (346nm) long-wave ultraviolet light source.
[0036] One of the fluorescent materials used in matching anti-counterfeiting marks is rare earth organic acid salts. The excitation band of this material is in the short-wave range of the ultraviolet spectrum (200nm-300nm). (365nm) no fluorescence can be observed when irradiated. Another kind of colorless fluorescent ink is stilbene-2,2'-disulfonic acid sodium salt. The spectral absorption wavelength of this substance is 346nm, the emission wavelength is 434nm, and the concentration is 40 %. It is colorless under normal light, and appears purple-blue under the long-wave (346nm) of the ultraviolet spectrum.
