【Abstract】 Recently, there have been increasing interests in the study of tunable photonic crystals (TPCs), in which the photonic band gap (PBG) can be tuned with environment changes. TPCs may represent a class of ideal candidates for fabricating optical sensors to monitor, measure, and display environmental variations in terms of PBG changes. In this work, we report a pH-responsive colloidal crystal assembled from composite spheres (PSMA-G4) with a core of poly (styrene-methyl methacrylate-acrylic acid) (P(St-MMA-AA) )spheres covered by pH-responsive polyamidoamine dendrimers.更多还原
