Aluminum nanoparticles were produced with using laser ablation method in water. In order to produce nanoparticles with different sizes, nanoparticles were made by three different intensity of 2, 2.5, and 3 J/cm2 of Nd:YAG laser at 1064 nm wavelength and 7 ns pulse width. Then PVA solution was doped with the equal amount of nanoparticle to make three thin films to studied effect of Aluminum nanoparticle size on the linear and nonlinear optical properties PVA films. Z-scan method was employed to measure the nonlinear refraction index of samples. Results show that with increasing the size of nanoparticles bandgap energy decrease and nonlinear refractive index increase. }, URL = {http://opsi.ir/article-1-828-en.html}, eprint = {http://opsi.ir/article-1-828-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2015} }
