摘要：

A method for fabricating gel-immobilized colloidal crystal spheres using microfluidics is reported. The diffraction color or photonic wavelength of the gelimmobilized colloidal crystal spheres can be adjusted by varying the particle concentration before gelation and tuned by external stimuli after preparation. © 2010 Wiley-VCH Verlag GmbH & Co.
