This paper illuminates the preparation of grating-like polystyrene latex monolayer structure,which can minimize the effects of the size deviation of spheres and the defect transfer on the accuracy as calibration samples for micro-scopes.The latex films are grown on freshly cleaved mica substrates by vertical deposition method.The concentration dependence of the structure and the topography of latex films is characterized by optical microscope,ultraviolet-visible transmission spectrum and scanning probe microscope.The origination of such a grating-like structure is also discussed.
