Abstract
Nanomaterials are of great interest due to their applications in many fields. The structural and efficacy of nano-materials depend strongly on the method applied for their synthesis. In this work, nanosized nickel oxide (NiO) particles were prepared by pulsed laser ablation (PLA) technique in 3% H 2 O 2 aqueous solution The structural and optical properties of the NiO were investigated by X-ray diffractometer (XRD), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscope (EDX), UV-Vis spectroscopy and Fourier-transform infrared spectroscopy (FT-IR). XRD analysis confirms that the phase is pure nickel oxide with lattice parameter = 0.42033 nm and 8 nm grain size while photoluminescence emission spectrum showed strong peak at 3.62 eV attributed to the band edge transition. FT-IR spectra depicts a strong band at ∼450 cm -1 which corresponds to the bending vibration of Ni-O bond. This work demonstrates that PLA is an effective method to control the size, impurity and minimal chemical waste generation which is the major problem with other wet chemical methods.
