There are many instances in the field of security where optically identifiable tags are used, examples of these include holograms, special inks/prints and conventional anti-tamper taggants. Unfortunately, there are a range of problems with these existing systems, none more so than their ease of clonability and lack of individuality. Thus, it is of great societal and technological significance to develop an optically addressable analogue of an UNO/PUF-like device that can overcome these problems by relying on quantum confinement and thus, the local atomic environment of the system. In this chapter, the possibility of this is suggested by using two-dimensional materials known as transition metal dichalcogenides (TMDs), which contain a direct band-gap in the visible range and therefore emit light that could be detected efficiently by a standard silicon CCD.
