Effect of Ni content on transmittance, reflectance and optical loss spectra of composite films based carbon

In this work, the optical constants of carbon films embedded by Ni nanoparticles under four deposition processing using mosaic targets made of carbon and nickel with Ni surface areas 1.78 - 4.64 %. A sharp decrease in the transmittance is observed at about around <400 nm attributed to the band edge absorption. The films exhibit a reflectance around <40% for the all range wavelength. It is shown that the waste of electrical energy as heat at 3.92 % has maximum value and with increasing energy it increases. The size of Ni nanoparticles for films deposited from 3.92 to 4.64 % increased
