Because of their exceptional physical and thermal properties, cellulose nanocrystals (CNCs) are a highly promising bio-based material for reinforcing fillers. Studies have revealed that some functional groups from CNCs can be used as capping ligand to coordinate with metal nanoparticles or semiconductor quantum dots during the fabrication novel complex materials. Therefore, through encapsulation electrospinning, perovskite-NC-embedded nanofibers optical stability demonstrated. The results indicate that, after continuous irradiation heat cycling, relative photoluminescence (PL) emission intensity CNCs-capped is maintained at ≈90%. However, PL both ligand-free long-alkyl-ligand-doped decrease almost 0%. These attributable formation specific clusters perovskite NCs along structure property improvement polymers. CNCs-doped luminous materials offer avenue stability-demanding optoelectronic devices other applications.
