EFFECT OF CEO2 NANOPARTICLES ON THE STRUCTURAL AND OPTICAL ‎PROPERTIES OF (SNO2:PD) FILMS PREPARED BY PLD TECHNIQUE‎

In this paper, pure and doped (SnO2:Pd ) films with CeO2 nanoparticles prepared by PLD ‎technique using a highly intense Nd:YAG laser beam at 600 mJ with a frequency of second ‎radiation at 1064 nm (pulse width 9 ns) repeating frequency (6 Hz) for 400 laser pulses incident ‎on the intended surface has been performed. The stabilized (SnO2:Pd) doped with cerium oxide ‎were used for deposition of the thin films on glass with thickness 200nm±05. Films of SnO2:pd ‎were prepared with different doping concentrations of CeO2(0, 0.05, 0.10,0.15,0.20 and 0.25) ‎wt. The FTIR and UV-Visible spectrophotometer were employed to investigate the structural, ‎and optical characteristics of the films, respectively. FTIR spectra of (SnO2:Pd)1-xCeO2x thin ‎films show seven peaks were assigned at wavenumber range from 2869.73 cm-1 belong to ‎stretching bond CH2 to 492.98 cm-1 belong to N-O which can be indicated by the vibrations ‎mode .The optical results show that transmittance decreased drastically by increasing the doping ‎ratio. In contrast with absorbance, it increased by increasing of the doping ratio of cerium oxide. ‎The optical energy gap was found to change systematic sequence with increasing of CeO2 ‎concentration. Also the optical constant with different CeO2 contents were determined.‎.
