摘要：The reversible variation in the observed stop band of a hydrogel-encapsulated crystalline colloidal array was achieved through the selective formation and destruction of -S-Pb-S- linkages within the hydrogel. A reversible 45 nm stop band shift could be achieved with a cyclical treatment of Pb2+ and then dithiothreitol solution. (C) 2012 Elsevier Inc. All rights reserved.
