The structure and optical properties of ag doped CdO thin film prepared by pulse laser deposition (PLD)‎

Abstract EN

At a temperature of 300 K, a prepared thin film of Ag doped with different ratios of CdO (0.1, 0.3, 0.5) % were observed using pulse laser deposition (PLD).

The laser, an Nd:YAG in λ=1064 nm, used a pulse, constant energy of 600 mJ ,with a repetition rate of 6 Hz and 400 pulses.

The effect of CdO on the structural and optical properties of these films was studied.

The structural tests showed that these films are of a polycrystalline structure with a preferred orientation in the (002) direction for Ag.

The grain size is positively correlated with the concentration of CdO.

The optical properties of the Ag :CdO thin film we observed included transmittance, absorption coefficient, and the energy gap in the wavelength range of 300-1100 nm.

The prepared films, direct energy gap is negatively correlated to concentration of CdO.
