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 Ag_n 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 Ag_n nanocluster absorption cross- sections (σ = 8 × 10^-15 cm²) and saturation intensities (I_sat = 200 W/cm² at 514.5 nm). Single molecule fluorescence experiments have elucidated the dynamics of AgO photoactivation and subsequent Ag_n nanocluster emission. Additionally, excitation, wavelength and intensity dependent dynamics are investigated. Results clearly show dependence on wavelength and intensity in Ag_n nanocluster creation and destruction.
