Abstract
Precursor decomposition and direct ink writing (DIW) technology were used to successfully prepare BCNO with complicated geometric shapes. PEG400DA photosensitive resin is employed as a printing ink binder and a carbon source for BCNO in this study. BCNO was prepared using various sintering temperatures and PEG400DA content, and BCNO monoliths with emission wavelengths of 442–529 nm can be prepared. The effects of these synthesis conditions on the structure and fluorescence properties of BCNO were investigated. BCNO monoliths can be employed as a suitable material for fluorescence anti-counterfeiting because of their good and controllable fluorescence properties.
