“…Comparative analysis indicates that the residual glow effect did not diminish, thereby substantiating the outstanding environmental stability of the SMSO. Conventional photovoltaic energy storage materials, [ 23 ] such as strontium aluminate, progressively undergo hydrolysis when exposed to water, leading to a gradual decline in afterglow performance. Addressing this issue typically entails the application of moisture‐resistant coatings, such as Al 2 O 3 or TiO 2 , which significantly increases production costs.…”

Mechanoluminescence is a smart light‐emitting phenomenon in which applied mechanical energy is directly converted into photon emissions. In particular, mechanoluminescent materials have shown considerable potential for applications in the fields of energy and sensing. This study thoroughly investigates the mechanoluminescence and long afterglow properties of singly doped and codoped Sr2MgSi2O7(SMSO) with varying concentrations of Eu2+ and Dy3+ ions. Subsequently, a comprehensive analysis of its multimode luminescence properties, including photoluminescence, mechanoluminescence, long afterglow, and X‐ray‐induced luminescence, is conducted. In addition, the density of states mapping is acquired through first‐principles calculations, confirming that the enhanced mechanoluminescence properties of SMSO primarily stem from the deep trap introduced by Dy3+. In contrast to traditional mixing with Polydimethylsiloxane, in this study, the powders are incorporated into optically transparent wood to produce a multiresponse with mechanoluminescence, long afterglow, and X‐ray‐excited luminescence. This structure is achieved by pretreating natural wood, eliminating lignin, and subsequently modifying the wood to overall modification using various smart phosphors and epoxy resin composites. After natural drying, a multifunctional composite wood structure with diverse luminescence properties is obtained. Owing to its environmental friendliness, sustainability, self‐power, and cost‐effectiveness, this smart mechanoluminescence wood is anticipated to find extensive applications in construction materials and energy‐efficient displays.

“…SrAl 2 O 4 -based phosphors are traditional long afterglow and typical mechano-luminescent materials that have many important applications in environmental displays and stress/strain sensing. 78 Huang et al 76 obtained the maximum twofold ML brightness enhancement by co-doping Eu( ii ) and Dy( iii ) in an SrAl 2 O 4 matrix and observed suitable stress-induced afterglow and stress-free afterglow characteristics. They made an ML speed bump using the SrAl 2 O 4 :Eu 2+ ,Dy 3+ composites, which exhibited evident light-emitting and light trails on the surface of the film after being run over by bicycles and car tires, as shown in Fig.…”

“…Among them, luminescence-based persistent luminescent (PersL) anti-counterfeiting materials have attracted widespread attention due to their easy implementation, good concealment, difficulty in replication, high emission intensity, multiple emission colors, long emission life, and applicability to mass production. [33][34][35][36][37] PersL materials have been widely studied and applied in the fields of special lighting, [38,39] light storage [40,41] and military engineering [42,43] because of their characteristics of continuous luminescence under dark conditions, however, the application in the field of dynamic anti-counterfeiting technology is rare. We have combined PersL materials and anti-counterfeiting applications and found that dynamic anticounterfeiting marking applications can be prepared.…”

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.
