Abstract

Nanocomposite thin films consisting of nanometer-sized Cu particles embedded in an amorphous Ba_0.5Sr_0.5TiO₃ matrix (Cu:BST) on Al₂O₃ (0001) substrates were fabricated by an alternating pulsed laser deposition method. The nanocomposite films containing Cu nanoparticles with a volume fraction of more than 5.4% showed a characteristic surface plasmon resonance (SPR) absorption band at ∼ 580 nm. The nonlinear optical properties of the Cu:BST nanocomposite film with a Cu volume faction of 5.4% were determined using the Z-scan method at the SPR wavelength. The magnitude of the third-order nonlinear susceptibility of the sample was calculated to be 9.737 × 10^{- 9} esu.
