Pd nanoparticles as new materials for acoustically induced non-linear optics

It was shown that the Pd nanoparticles (NP) deposited on ITO substrate by seed-deposited technology show substantial acoustically induced non-linear optical effects. The effects appear at low temperatures. It was established that the Pd films and ITO substrates do not give the sufficiently high effect. Coating of the Pd NP on the Pt ones gives additional enhancement of the effect. The NP obtained using different technological regimes shows high sensitivity to the acoustically induced SHG. So this method may be recommended like a high sensitive method for detection of the Pd NP.
