Boron Nitride - a wide bandgap insulating material can be suitably tuned to produce boron nitride nanosheets (BNNS) with strengthened properties. Bulk material upon exfoliation and surface treatment could make structural improvements leads to the change in electrical and optical properties. The present work is focused to produce BNNS followed by chemical treatment of its surface in order to tune its optical properties. Herein BNNS is produced through solvent assisted exfoliation and property tuning via fluorination. The prepared samples were subjected to FTIR, Raman, XRD and UV studies.
