Nanoassembly of CdTe nanowires and Au nanoparticles: pH dependence and reversibility of photoluminescence
Lee JB, Chen HX, Koh KN, Chang CL, Kim CM, Kim SH
Radial organized nanohybrids that are composed of Au nanoparticles (NPs) surrounding CdTe nanowires (NWs) via bioconjugation of streptavidin (SA) and D-biotin (B) were prepared to compare with the non-conjugated NWs. Two respective NW-containing hybrids with/without Au bioconjugation presented the same pH dependence except for photoluminescence (PL) reversibility. It would be explained that the chemical modification of NW surface can be retarded due to the geometric hindrance of acidic fluids in nanoscale regime and the loosely encapsulated Au NPs on NWs assisted to induce the luminescence recovery from collective resonance of excitons and plasmons in nanohybrids.
Keywords: Nanowires; Nanoparticles Bioconjugates; Luminescence Enhancement; Collective Effects; pH Dependence
