Abstract 

Polystyrene photonic crystal template was obtained by monodispersing polystyrene microspheres using vertical deposition method. CdTe quantum dot was synthesized in aqueous solution and modified by 3-mercaptopropionic acid (MPA). Precursor solution was a mixture of functional monomers (vinyl carboxylic acid and acrylic amide), cross linker (N,N'-methylene bisacrylamide) and initiator (ammonium persulfate). Then CdTe quantum dot-immobilized hydrogel photonic crystal was fabricated by filling precursor solution containing CdTe quantum dot into the interstitial spaces of polystyrene photonic crystal templates, followed by a thermal polymerization. The prepared material was characterized and exhibited a three-dimensional, highly-ordered face-centered cubic structure with a photonic band gap and fluorescent property.
