Abstract

A method for the determination of thethickness of gold layerontop of silversubstrate hasbeen developed. Various
samples having silver asthe substrate were coated with gold for different time durations by ion sputtering. The gold
to silver X-ray counts ratios were determined using an energy dispersive spectrometer equipped to the scanning
electronmicroscope. Agraphplotted betweenthegoldto silverX-raycountsratiosandthethickness ofthe gold layers
enables to determine the gold layer thickness of anunknown sample by merely measuring its gold to silver X-ray
counts ratio and then extrapolating this ratio to itscorresponding thickness.
