Researchers at National Institute of Advanced Industrial Science and Technology (NIAIST) Report New Data on Lasers and Photonics (Surface plasmon resonance tunability in VO2/Au/VO2 thermochromic structure)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators publish new report on Lasers and Photonics. According to news reporting from Nagoya, Japan, by VerticalNews journalists, research stated, "Nanometal-VO2 composite systems can exhibit a reversibly tunable localized surface plasmon effect under external temperature stimuli due to the temperature-sensitive dielectric function of the thermochromic VO2 thin film. In order to improve the tunability range and enhance the resonance shift magnitude Delta lambda(SPR)), the VO2/Au/VO2 sandwich structure was deliberately designed here."

The news correspondents obtained a quote from the research from the National Institute of Advanced Industrial Science and Technology (NIAIST), "The plasmonic and thermochromic characteristics of this structure were powerfully dependent on the gold deposition time (t). By varying this parameter, the resonance wavelength (lambda(SPR)) of the semiconductor phase can be regulated from the visible range (686 nm) to the near-infrared range (1482 nm) and a maximum Delta lambda(SPR) of 714 nm can be achieved at t = 3.5 min."

According to the news reporters, the research concluded: "This study may provide insights into plasmonic noble metal nanoparticles on a thermochromic VO2 matrix and offer potential applications in temperature-sensitive nanodevices."
