“…To improve the security of the PUF labels, the scattering spectra of the diamond particles can be further employed. The scattering spectra of diamond particles have been shown to be highly sensitive to topological structures such as size, shape, and crystallinity 59 , 60 . As a result, it is impractical to duplicate them with identical spectra accurately.…”

The growing prevalence of counterfeit products worldwide poses serious threats to economic security and human health. Developing advanced anti-counterfeiting materials with physical unclonable functions offers an attractive defense strategy. Here, we report multimodal, dynamic and unclonable anti-counterfeiting labels based on diamond microparticles containing silicon-vacancy centers. These chaotic microparticles are heterogeneously grown on silicon substrate by chemical vapor deposition, facilitating low-cost scalable fabrication. The intrinsically unclonable functions are introduced by the randomized features of each particle. The highly stable signals of photoluminescence from silicon-vacancy centers and light scattering from diamond microparticles can enable high-capacity optical encoding. Moreover, time-dependent encoding is achieved by modulating photoluminescence signals of silicon-vacancy centers via air oxidation. Exploiting the robustness of diamond, the developed labels exhibit ultrahigh stability in extreme application scenarios, including harsh chemical environments, high temperature, mechanical abrasion, and ultraviolet irradiation. Hence, our proposed system can be practically applied immediately as anti-counterfeiting labels in diverse fields.

“…Nanotechnologies based on materials with a high refractive index have been actively developed in recent years [12]. Optical elements in these structures are much smaller in size than the light wavelength, and the structures themselves are characterized by size parameters smaller or on the order of unity: q m ~ 1 The optical properties of these structures are generally determined by the first three (dipole, quadrupole, and octupole) Mie resonances, due to which the radiative properties of nanoantennas can be controlled [12][13][14]. It is of fundamental importance to use wave equations to describe these structures.…”

The growing prevalence of counterfeit products worldwide poses serious threats to economic security and human health. Developing advanced encryption materials with physical unclonable functions offers an attractive defense against counterfeiting. Here, we have successfully developed multimodal, dynamic and unclonable anti-counterfeiting labels based on high-quality diamond microparticles containing silicon-vacancy (SiV) centers. These chaotic microparticles were heterogeneously grown on silicon substrate by chemical vapor deposition, facilitating scalable and massive fabrication at low cost. Due to the non-deterministic nature of this growth method, the intrinsically unclonable function has been introduced by the randomized features of each individual particle. In particular, the extremely stable signals of SiV photoluminescence (PL) and light scattering from diamond microparticles are shown to enable high-capacity optical encryption. Moreover, time-dependent encryption has been achieved by dynamically modulating the SiV PL signals and/or controlling packed patterns of diamond microparticles via post air oxidation. Exploiting the robustness of diamond, the developed diamond-based labels exhibit ultrahigh stability in different extreme application scenarios, including harsh chemical environments, high temperature, mechanical abrasion, and UV light irradiation. Our proposed system, with its extreme randomness, multimode and dynamic encryption capability and outstanding robustness, can be practically applied immediately as anti-counterfeiting labels in diverse fields.
