摘要
Nickel nanoparticles (Ni-NPs) were successfully synthesized and attached on indium tin oxide (ITO) substrate by two different methods: from solution reduction process by using sodium borohydride (NaBH(4)) as reducing agent in the presence of poly(N-vinilpyrrolidone) (PVP) as protective and stabilizing agents and by polyol process under ethylene glycol EG as a solvent. The results indicated that the samples prepared in aqueous solution show the occurrence of face-centered cubic metallic nickel nanoparticles with a medium diameter of similar to 31nm and good size dispersion compared to the preparation in EG that revealed large size similar to 150 nm. The dynamics of the nanoparticle's growth in the solvents and comparison with optical absorption is presented.
