In this study, boron nitride nanosheets (BN–NS) were prepared through exfoliation of bulk BN powder and efficacious incorporation of Ni (dopant material) was achieved using hydrothermal methodology. Hexagonal phase of BN (h-BN) was detected using x-ray difractometer (XRD). The presence of used chemicals was identified by functional group analysis through fourier transform infrared spectroscope (FTIR), which indicated strong vibrations for B–N and B–N–B. Optical examination carried out through absorption spectra extracted from UV–vis. spectroscopy point out absorption at deep UV state. Raman spectra were obtained to affirm structural molecular fingerprints of BN. Excitons behavior was studied using photoluminescence (PL) spectroscope. Scanning (SEM) and transmission electron microscopes (TEM) were used to investigate morphological and microstructural features while interlayer spacing …
