METHOD FOR IN-SITU MANUFACTURING MONODISPERSE SPHERICAL PHOTONIC CRYSTALS WITH SINGLE OR MULTI-COLORS USING MICROFLUIDIC DEVICES

摘要

The present invention is a method for manufacturing monodisperse spherical photonic crystals with single or multi-colors with a uniform size, which comprises: preparing microfluidic devices consisting of glass tubes; treating a colloidal dispersion capable of being photo-polymerized to generate liquid drops with a uniform size in water using the prepared microfluidic devices; and passing the prepared liquid drops with a uniform size through a region exposed to the UV located downstream of the fluidic devices to carry out photo-curing. The present inventions include a method for in-situ manufacturing of monodisperse spherical photonic crystals with a uniform size using microfluidic devices consisting of glass tubes, a method for manufacturation of monodisperse spherical photonic crystals with single or multi-colors as well as evaluation of optical properties of the monodisperse spherical photonic crystals manufactured by the above method and electrical rotation of the monodisperse spherical photonic crystals. A monodisperse spherical photonic crystalline structure formed according to the present invention is preferably applied to a variety of applications including, pixels of reflex displays, labels for detection of biological molecules, etc.
