The Effect of Au Nanoparticles on the Structural and Optical Properties of (NiO:WO3) Thin Films Prepared by PLD Technique

In the present investigation, (NiO:WO3 ) thin films were deposited at RT onto glass substrates using PLD technique employing focused Nd:YAG laser beam 600 mJ with a frequency second radiation 1064 nm (pulse width 9 ns) repetition (6 Hz), for 400 pulses incident on target surface .The structural, morphological and optical properties of doped different concentration Au content (0.03, 0.05, 0.07) examined X-ray diffractometer(XRD), Atomic Force Microscope(AFM) , UV–Vis spectrophotometer . The results show that amorphous small peaks appearing when AuNPs XRD NiO:WO3 enhanced increasing crystalline size was calculated Debye Scherer formula found to decrease from 6.6 undoped 3.4 (NiO:WO3) increase x=0 x=0.07 preferred orientation (200). All samples have cubic structure. Also, showed affects morphology. From AFM analysis, it roughness average diameter change adding structure, highest value occurring ratio 0.03 equal 7.58 81.02 nm, respectively. used investigate transmission. It increased, transmittance decreased.
