(a) Room temperature PL spectra of BZnO synthesized at 60 °C, using 0.1 M Zn(NO3)2.6H2O and drop-wise addition of NH4OH up to pH = 7.5 with addition of 3 wt% PVP (The Gaussian peaks marked as green colour at the bottom of the fitted curve marked with red colour). (b) Room temperature PL spectra of FZnO synthesized at 60 °C, using 0.075 M Zn(NO3)2.6H2O and drop-wise addition of NH4OH up to pH = 7.5 with addition of 3 wt% PVP (The Gaussian peaks marked as green colour at the bottom of the fitted curve marked with red colour).
