Abstract

The potential of a novel silver-silver oxide system for optical data storage with fluorescent readout has been discovered and developed. These properties arise from photolytic production of highly fluorescent single Agn molecules (n = 2-6 atoms) from silver oxide. Optical experiments with a 514.5 nm Ar+ laser and a 100W Hg lamp allow determination of single Agn nanocluster absorption cross- sections (σ = 8 × 10-15 cm2) and saturation intensities (Isat = 200 W/cm2 at 514.5 nm). Single molecule fluorescence experiments have elucidated the dynamics of AgO photoactivation and subsequent Agn nanocluster emission. Additionally, excitation, wavelength and intensity dependent dynamics are investigated. Results clearly show dependence on wavelength and intensity in Agn nanocluster creation and destruction.
