In this work thin silver oxide layers (AgO_x) were prepared by reactive sputtering of a silver target in oxygen containing atmosphere.We report a gradual composition change of the deposited layers with increasing oxygen concentration from Ag over Ag_2O to AgO and furthermore that dispersed silver clusters are present even up to high O_2 concentrations.Raman- along with IR-spectroscopy and ellipsometric measurements reveal specified compounds at defined oxygen concentrations.Optical transmission and reflection measurements as a function of temperature show that these compounds exhibit phase transitions (i.e.AgO decomposes to Ag_2O and finally to Ag), connected to considerable refractive index changes.This work was done with respect to super-Resolution Near-Field Structures where these effects are exploited to realize ultra high optical data storage in combination with magneto-optical and phase change recording materials.
