As populations expand worldwide, medical care will need to diversify its data collection
techniques to be able to provide adequate healthcare to global populations, this can be …

Traditional luminescent inks used in anti-counterfeiting applications usually consist of single-
mode photoluminescence (PL) or up-conversion luminescence (UCL) materials, which are …

A simple D-shaped photonic crystal fiber (PCF) based surface plasmon resonance (SPR)
biosensor is proposed for refractive index sensing in visible to near infrared (IR) region. A …

We propose and numerically characterize the optical characteristics of a novel photonic
crystal fiber (PCF) based surface plasmon resonance (SPR) sensor in the visible to near …

The never‐ending struggle against counterfeit demands the constant development of
security labels and their fabrication methods. This study demonstrates a novel type of …

Owing to the large coding capacity and high confidentiality, dual‐mode or multimode
anticounterfeiting fluorescent materials are gradually substituting traditional single‐mode …

Currently, illegal counterfeiting activities are increasing with the continuous developments of
