Fluorescent Ag nanoclusters in glass induced by an infrared femtosecond laser

Fluorescent/luminescent detection of natural amino acids by organometallic systems

“…Biological thiols captured Hg 2+ ions via a robust Hg-S interaction, which prevented Hg 2+ -induced quenching and resulted in Au NC fluorescence.Insert Figures 85-87 Herein5.2.2.2. Polymer-Templated Silver NanoclustersShang and Dong produced water-soluble Poly(methacrylic acid, sodium salt) (124)-templeted Ag the submerged and quasi-continuum 5d band to the lowest unoccupied conduction band of the Ag NCs[181][182]. With increasing Cys concentration, the fluorescence emission of the 124-Ag NCs decreased gradually and was almost completely quenched in the presence 6.0×10 -5 M Cys with an obvious red-shift in the emission maximum.…”

Optical Data Storage in Photosensitive Glasses and Spin State Transition Compounds

“…A wide band centered at 580 nm is observed. These spectral properties can be attributed to the photoinduced silver nanoclusters (Dmitryuk et al, 1996;Dai et al, 2007). The optical properties of the silver nanoclusters are studied for different irradiation conditions by white light, epiuorescence and third-harmonic generation (THG) microscopy.…”

UV–Irradiation Induced Synthesis of Fluorescent Poly (Acrylic Acid) Stabilized Silver Clusters

“…Their fluorescence is mainly due to the inter-band electronic transition from the submerged and quasi-continuum 5d band to the lowest unoccupied conduction band of the clusters [2]. Previous studies show that fluorescence was attributed to the coupling of photo-activated clusters and silver oxides [3].…”
