Abstract:Many potential applications in optics and nanotechnology require arrays of spherical particles with dozens of microns diameter, but it is not easy to format microspheres in this scale using existing technologies, especially for large-area application. In this paper, we report that microspheres sized from 40 to 80 μm can be regularly arranged in arrays with the aid of micro-ridges generated by pulsed nanosecond (ns) laser texturing. After experimental comparison, it is known that final formation of microspheres… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
