Let It Shine: A Transparent and Photo luminescent Foldable Nanocellulose/Quantum Dot Paper

Exploration of environmentally friendly light-emitting devices with extremely low weight has been a trend in recent decades for modem digital technology. Herein, we describe a simple suction filtration method to develop a transparent and photoluminescent nanocellulose (NC) paper, which contains ZnSe quantum dot (QD) with high quantum yield as a functional ZnSe QD can be dispersed uniformly in NC, and a quite low coefficient of thermal expansion is determined for the resultant composite paper, suggesting its good dimensional stability. These results indicate that the meeting of NC with ZnSe QD can bring a brilliant future during the information age.
