[Figure 3] Photograph of a color image displayed from a core@multi-shell upconversion nanoparticle-polymer composite.

Caption

(Top left) Photograph of a transparent polymer composite synthesized by dispersing core@multi-shell upconversion nanoparticles in a polydimethylsiloxane (PDMS) polymer.

(Right) Photographs of various color images realized upon application of near-infrared light to the core@multi-shell upconversion nanoparticle-PDMS polymer composite, demonstrating that it is possible to achieve color displays of any desired shape using a near-infrared light source and the upconversion nanoparticle-polymer composite.
