Photonic Crystals Based on ZIF-8 Nanoparticles with Embedded Carbon Dots for Optical Information Encryption

Lan-Xing Gao,
Yun-Liang Ji,
Wei-Long Bi
et al.

Abstract: Photonic crystals (PCs), composed of nanoparticles as building blocks, possess a unique photonic band gap (PBG). While incorporated with fluorescent materials such as quantum dots or dyes, the PCs could provide opportunities to expand their applications in anticounterfeiting and optical information security. Selecting suitable nanounits that can act as building blocks for constructing PCs and meanwhile serve as ideal carriers for fluorescent materials to maintain their intrinsic fluorescent properties has beco… Show more
