Abstract
NiO nanoparticles were synthesized via a simple sonochemical method using NiCl2 as a precursor. Ternary sodium zinc borate glasses doped with the synthesized nano-sized NiO or commercial readymade NiO have been prepared by the conventional melt and annealing method. The spectroscopic behavior of the prepared NiO—doped glasses has been evaluated applying, absorption in UV–Visible region, semiconducting investigation, photoluminescence activity and building structural units by FTIR. X-ray diffraction indicated the amorphous nature of the prepared glasses. UV–Visible absorption spectrum reveals visible absorption bands of Ni2+ at 425 and 815 nm. A sharp intensive emission peak centered at about 652–668 nm was observed. The optical parameters indicated that the nano-sized NiO doped glass could be used in semiconducting applications. Infrared absorption measurements indicated that both triangular and tetrahedral borate (BO3, BO4) are the main building structural units of the prepared glasses and the addition of NiO causes no variations in the number or position of infrared absorption bands.
