研究了双光子激发硝酸银在聚乙烯吡咯烷酮(PVP)基质中形成的二维结构的形态行为。在显微镜平台上制作了深度方向两个不同位置的二维结构。用原子力显微镜(AFM)、扫描电子显微镜(SEM)、能量色散X射线能谱(EDX)和X射线光电子能谱(XPS)对所得结构进行了表征。AFM测量表明，在盖片上有光致结构。EDX和XPS测试表明，银离子被光还原，光还原后的银与PVP相互作用。(C)2013爱思唯尔B.V.保留所有权利。
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. (C) 2013 Elsevier B.V. All rights reserved.
