Double network hydrogel embedded with quantum dots: Enhanced visual performance for holographic 3D display

Transparent double network hydrogels incorporated with quantum dots are promising display medium for holographic 3D display. In this work, we found that the combination of aqueous quantum dots and double network hydrogel is an advantageous strategy to fabricate free-standing bulk nanocomposites with enhanced mechanical properties . The double network hydrogel with colloidal quantum dots can construct high quality images with peak signal-to-noise ratio value up to 28.48, enabling them to be potential display mediums for holographic 3D display.
