| Abstract: |
| In this study， the inorganic CsPbBr3 quantum dots （BVA-CsPbBr3 PQDs） with uniform size， controllable morphology， and high fluorescence quantum yield （PLQY=58.1%） were synthesized by adopting the thermal injection method， and the 5-bromovaleric acid （BVA） was used to replace the oleic acid （OA） as the surface ligand in the synergic action with oleylamine （OLA）. Based on that， the excellent mechanical properties and abundant porous structure of cellulose nanofibers （CNF） were combined to prepare the PQDs@CNF composite reinforced films， which enabled the BVA-CsPbBr3 PQDs to be uniformly dispersed and firmly anchored in the CNF fiber network， effectively avoiding the agglomeration of the PQDs and enhancing the mechanical strength of the PQDs@CNF composite reinforced films. The results showed that the PQDs@CNF composite reinforced films had excellent luminescence and mechanical properties， which not only retained the original high photoluminescence intensity of BVA-CsPbBr3 PQDs， but also had the environmental adaptability and stability due to the combination with CNF. |
