Free-Standing Iridescent Films of Cellulose Nanocrystal Doped with Eu³⁺ and Tb³⁺ Ions for Photonic Applications.

ABSTRACT: The simultaneous integration of iridescence and light emission into a photonic material is an attractive proposal for designing novel optical devices. These properties could be controlled by the action of chiral nematic liquid crystals, and the self-assembly of cellulose nanocrystals is a smart methodology for the development of this new material. Herein, bacterial cellulose (BC) has been used as a cellulose source, mainly due to its biocompatibility, nontoxicity, and high purity. In this context, cellulose nanocrystals (CNCs), obtained by acid hydrolysis methodology, have received significant interest in the production of new optical materials due to their controllable chiral nematic self-organization. The work aims to obtain new iridescent films based on CNCs with adjustable cholesteric
