Nano Powder Sample Preparation with Improved Spin-Coating Method

Deposit-dip-spin(DDS) coating method,a composite nano-powder sample preparation method for atomic force microscope(AFM) measurement is introduced.DDS method ensures the deposition of enough particles on mica substrate to well simulate the distributing of the particles in the sol.While rapid evaporation speed disperses and freezes particles on a certain position.Clear AFM images were(obtained) from PbZr_(0.90)Ti_(0.10)O_3-Fe_(0.003) nano powder sample prepared by DDS method.Data analysis of AFM images and scanning electron microscope(SEM) photo well show the topographic details and grain size of particles.And the(statistical) result matches with transmission electron microscope(TEM) image and(X-ray) diffraction(XRD) data.
