Optical and structure characteristics of diamond like-carbon thin films produced by PLD

Abstract EN

The utilizing of Nd : YAG laser (wave length-1064 nm) in the pulsed laser-deposition-PLD for placing diamond-like carbon DLC-film on glass substratum at the normal temperature of room.

the composition and morphology of the surface for the atomic force microscopy (AFM), synthesized film and Fourier transform infrared FTIR-spectra for DLC utilized to know the presence of bonding were characterized by scanning electron microscopy-SEM and energy dispersive x-ray-EDX.

deposited DLC-film has a compact structure of dense grains, and the film contained irregular shape pa rticles (clusters) of DLC.

FTIR-spectra confirmed that the DLC-film contains carbon atoms with sp3- hybridization.were investigated in optical properties with the results concerning the transmittance, absorption coefficient-(α), optical energy-gap, reflectance-R, extinction coefficient-k and refractive index-n.
