We have produced nanoparticulate Pd–Au (88–12at.%) thin films using, for the first time, spark ablation and inertial deposition on glass substrates. Films having thicknesses that range from ca. 150 to 200nm exhibit high enough contrast (i.e., range of optical transmittance) and negligible hysteresis...
