Abstract
in the core and the emitters in the shell were investigated. Moreover, these optimized upconversion nanoparticles can be used in the multicolor latent fingerprint recognition with the secondary fingerprint details easily achievable, showing great potential in the anti-counterfeiting of fingerprints for information security.
