Manipulating fluorescence color to achieve patterned function may access to many applications and remains some challenges. In this work, we provide an effective way to manipulate upconversion fluorescence through the photonic crystals. The structure of the photonic crystals (PCs) has a regulatory effect on upconversion fluorescence. We assembled NaYF4:Yb3+/Er3+ upconversion nanoparticles (UCNPs) with SiO2 and CdS photonic crystals respectively to obtain the photonic crystals/upconversion nanoparticles (PCs/UCNPs) composites. We studied the manipulating mechanism of two kinds of photonic crystals on upconversion fluorescence, and realized patterning application. This study provides a new way to realize information coding, patterned display of fluorescence manipulating.
