Counterfeiting and inverse engineering of security and confidential documents, such as
banknotes, passports, national cards, certificates, and valuable products, has significantly …

This review summarized the applied techniques and applied nanomaterials (NMs) for the
progress of latent fingerprints (LFPs) images on several surfaces. Used numerous types of …

Fluorescent patterns showing the unique color change in response to external stimuli are of
considerable interest for their applications in anti‐counterfeiting. However, there is still a lack …

The improper handling of decrypted information can lead to the leakage of confidential data.
Thus, there is increasing interest in the development of self‐erasing decrypted data. Herein …

Upconversion luminescence of nano-sized Yb3+ and Tm3+ codoped rare earth phosphates,
that is, LaPO4 and YPO4, has been investigated under high-pressure (HP, up to∼ 25 GPa) …

Encoded nano-structures/particles have been used for barcoding and are in great demand
for the simultaneous analysis of multiple targets. Due to their nanoscale dimension (s), nano …

A new covert luminescent anticounterfeiting (AC) technology was developed by employing
combinatorial chemistry and concentration-dependent stimulus-responsive luminescent …

Fluorescent photochromism has been applied as an attractive approach for the production of
effective authentication substrates to show dual-mode secure encoding. In the current study …

The increasing demands for optical anti-counterfeiting technology require the development
of versatile luminescent materials with multiple models and tunable photoluminescence …

Conventional optical anti-counterfeiting strategies are based on the single-color emission,
which are easily deciphered and thus greatly limited in the application of information …
