Carbon Dots/SiO₂ Fluorescent Photonic Crystals for Anti-Counterfeiting

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(6), С. 6547 - 6555

Опубликована: Март 6, 2024

Composite materials that combine quantum dots and photonic crystals can produce some complex anti-counterfeiting patterns, which solves the problems of simple encoded information low levels monochromatic materials. Here, we prepared a type carbon dots/silicon dioxide (CDs/SiO2) fluorescent crystal with both angle-dependent structural color fluorescence properties. First, silica nanospheres 220, 250, 280 nm were using Stöber method by changing ethanol amount. Then, monodispersed CDs/SiO2 composite synthesized one-pot microwave hydrothermal method. The surface morphology, monodispersity, phase structure, other properties explored. Experiments showed thin film formed after natural deposition microspheres had green while retaining original color. In addition, intensity was significantly improved compared to CDs. This study provides valuable experimental scheme for preparing multifunctional ideas expanding application fields crystals.
