Near-infrared-excitable perovskite quantum dots via coupling with upconversion nanoparticles for dual-model anti-counterfeiting

摘要

Here, we report the design of upconversion nanoparticle-coupled perovskite quantum dots that are full-color tunable under single near-infrared (NIR) excitation. Consequently, we demonstrate the use of these hybrid nanomaterials in printable, NIR-excitable, dual-model anti-counterfeiting.
