Our earlier developed experimental technique was used to
prepare spatially located arrays of bimetallic AuAg
nanoparticles in the near-surface region of glass,
demonstrating surface plasmon resonance (SPR)
characteristics that vary over a wider range compared to
monometallic Au, Ag particles or corresponding thin films,
is presented. The suggested technique is based on the UV
laser irradiation (λ = 193 nm) of the glass surface
preliminary doped with silver ions and then sputter coated
by a thin gold layer. For each sample, the different
number of laser pulses was applied in the range from 0 to
1000, with pulse repetition rate of 1 Hz.
The main aim of this study is the determination of the local
atomic structure of silver ions in a glass by using x-ray
absorption spectroscopy.
