This research presents a new approach to create two-color luminescent physically unclonable functions (PUFs) using an organic luminophore with tunable emission colors. These PUFs offer high security and stable performance, significantly enhancing anti-counterfeiting capabilities by exponentially increasing encoding capacity through dual-color integration and complex pattern formation.
