Tunable Tri-Channel Orthogonal Full-Color Luminescence in Nanostructure toward Anticounterfeiting and Information Security (Laser Photonics Rev. 19(8)/2025)

Abstract

Multi-Color Upconversion

In article number 2401652, Xinyu Ye, Bo Zhou, and co-workers report the rational design of a simple core-shell nanostructure for tunable dual-mode orthogonal luminescence. The red-green-blue (RGB) and full-color switchable output with high color-purity is easily achieved under multi-wavelength selective excitation, showing great promise in advanced anti-counterfeiting and information security.
