“…Compared with the traditional static luminescence anti-counterfeiting technology, dynamic PersL anti-counterfeiting technology is based on luminescent printing and other anti-counterfeiting technologies by making specific luminescent signs, which do not disappear immediately when removed under different stimuli and conditions, but continue to glow for a certain period of time, thus obtaining different display colors or patterns and realizing a dynamic change in the anti-counterfeiting process with the specificity of material design. [44][45][46] On the one hand, the PersL anti-counterfeiting technology can be used alone to achieve dynamic anti-counterfeiting effect. On the other hand, the PersL anti-counterfeiting Long afterglow anti-counterfeiting technology can be combined with other anti-counterfeiting technologies to form a multi-modal and multi-process anti-counterfeiting, which can produce reversible changes in the chemical structure or solid structure according to external stimuli to enhance the anti-counterfeiting effect, thus making the long afterglow materials have a dynamic light-emitting phenomenon by virtue of changes in afterglow intensity and color.…”

Persistent luminescent materials can continue to emit light after stopping excitation, and their stored energy is gradually released during the decay time after persistent emitting, which makes the color and luminance changes in slow decay and plays an important role in protecting information and combating forgery. When combined with other anti‐counterfeiting technologies to form a multi‐modal and multi‐process anti‐counterfeiting design, it perfectly hides the real information and has a broad application prospect in anti‐counterfeiting logo design. A brief overview of the design of three different persistent luminescence‐based anti‐counterfeiting applications in unimodality to achieve information encryption in the time dimension. The energy stored in the trap is studied to be released by different physical stimuli and applied to stimulus‐like responsive persistent luminescent materials, and the design of persistent luminescence anti‐counterfeiting applications based on many different processes in dual‐modality, obtaining the dynamic anti‐counterfeiting effect of multiple processes in multiple modes. This work reviews the research background of persistent luminescent materials in the field of anti‐counterfeiting in recent years, compares the important breakthrough progress of persistent luminescent materials applied to anti‐counterfeiting research, and finally puts forward the current problems, future challenges, and development directions.

“…When the external energy stops irradiating, the stored energy can be slowly released in the form of light to achieve non-electric luminescence; therefore, it is also known as luminous material [1,2]. At present, several green long afterglow phosphors with excellent persistence properties have been reported such as SrAl 2 O 4 :Eu 2+ ,Dy 3+ [3], Li 2 MgGeO 4 :Mn 2+ [4], Ca 2 MgSi 2 O 7 :Eu 2+ ,Dy 3+ [5], Ba 2 SiO 4 :Eu 2+ ,Ho 3+ [6], Ga 4 GeO 8 :Tb 3+ [7], Sr 3 Ga 4 O 9 :Tb 3+ [8], and Zn 2 SiO 4 :Mn 2+ ,Pr 3+ [9]. Among them, SrA1 2 O 4 :Eu 2+ ,Dy 3+ is one of the most studied green long afterglow phosphors.…”

With the whole society’s demand for intelligence, the smart highway has become the inevitable trend of road development. Luminescent road marking made of long persistent luminescent coating is a new type of functional marking that is designed with long afterglow luminescent material as the raw material and has many features such as safety, beauty and energy saving. Here, SrA12O4:Eu2+,Dy3+ green long afterglow phosphors were prepared using a high-temperature solid state method. The green phosphors obtained at 1350 °C have two traps with a shallow trap depth of 0.66 eV and a deep trap depth of 0.8 eV. The green afterglow can be seen in the dark for more than 8 h after sunlight excitation for 2 h. The green long persistent luminescent coatings were synthesized using the blending method. The uniformity of each component can be improved by adding 1.25% SiO2 into the luminescent coatings. The addition of 3.5% CaCO3 will improve the compactness of the coatings and reduce water absorption. After soaking in water for 120 h, the afterglow intensity of the coating decreases to 76% of the original, showing good water resistance. After daylight excitation in different weather conditions (cloudy, sunny, rainy), the afterglow can reach more than 5 h; therefore, it can be applied to a smart highway.
