Studies from Federal University in the Area of Physics Research Reported (Optical properties of ZnO and Al2O3 implanted with silver ions)

July 8, 2014



By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Physics Research. According to news reporting from Tatarstan, Russia, by VerticalNews journalists, research stated, "ZnO and Al2O3 samples implanted with 30-keV silver ions with fluences in the interval (0.25-1.00) x 10(17) ions/cm(2) are studied by the method of optical photometry in the visible part of the spectrum. The optical transmission spectra of the implanted samples exhibit a selective band associated with surface plasmon resonance absorption of silver nanoparticles."

The news correspondents obtained a quote from the research from Federal University, "The intensity of this band nonmonotonically depends on the implantation fluence. The silver ion depth distribution in the samples is calculated. It is shown that the non-monotonicity observed in experiments is due to an increase in the substrate sputtering ratio with increasing implantation fluence. It is found that vacuum thermal annealing of the implanted Al2O3 layers up to 700A degrees C causes a considerable narrowing of the plasmon absorption bandwidth without a tangible change in its intensity. At higher annealing temperatures, the plasmon absorption band broadens and its intensity drops."

According to the news reporters, the research concluded: "Annealing of the ZnO films under such conditions causes their complete vaporization."
