Progress in Luminescent Materials for Anti-counterfeiting Labels(Invited)
At the end of this review, the present status of the luminescence anti-counterfeiting materials was concluded. The problems and obstacles to developing luminescence anti-counterfeiting labels were summarized. Some ideas for future progress were also proposed. It was figured out that the emission wavelengths for the present luminescence anti-counterfeiting materials are mainly in the visible region, thus resulting in easy counterfeiting and cloning. Therefore, developing novel luminescence anti-counterfeiting materials with emitting wavelengths other than visible wavelengths may be a good proposal. In many articles, more than one stimuli source were used, thus in fact is not a good way since the multi-excitation sources would result in complicated identification and high cost. Therefore, developing chemical-assisted luminescence anti-counterfeiting materials is more significant and meaningful. It should also be pointed out that the luminescence anti-counterfeiting materials with similar spectral properties to the commercialized phosphors are useless and dangerous since the counterfeiting and cloning behaviors are easy by using the commercialized phosphors in this sense. Finally, the combination of online and offline identifications is suggested while the 5G technique is widely used.
