Abstract

We studied the morphological behavior of two-dimensional (2D) structures fabricated by two-photon excitation of silver nitrate in poly(N-vinylpyrrolidone) (PVP) matrix. The 2D structures at two different positions toward depth direction were fabricated on a microscope stage. Obtained structures were investigated using an atomic force microscopy (AFM), a scanning electron microscopy (SEM), an energy dispersive X-ray spectrometry (EDX), and an X-ray photoelectron spectroscopy (XPS). AFM measurement showed the photo-induce structure on a cover slip. EDX and XPS measurements showed that the silver ion was photo-reduced and the photo-reduced silver was interacted with PVP, respectively.
