## Description

- description: " Irradiation temperature (IT) dependence of the elongation efficiency
    of vanadium nanoparticles (NPs) in SiO2 was evaluated: The samples were irradiated
    with 120 MeV Ag^9+ ions to a fluence 1.0 X 10^14 ions/cm2 at each IT between 300
    K and 591 K, while the measurements were performed at room temperature. The vanadium
    was selected for the NP species because of the highest bulk m.p. of 1890 C among
    all the species of the elemental metal NPs in which the shape elongation was observed.
    The highest m.p. could contribute negligible size changes of NPs against inevita-ble
    exposure to high temperatures for the IT dependence measurements. The elongation
    of V NPs was evaluated qualitatively by transmission electron microscopy (TEM)
    and quantitatively by the optical linear dichroism (OLD) spectroscopy. The electron
    microscopy studies showed a pronounce elongation of NPs with SHI irradiation at
    the elevated temperatures. The OLD signal was almost constant, or even slightly
    increased with increasing the IT from 300 K to 591 K. This IT dependence provides
    a striking contrast to that of the ion hammering (IH) effect, which pre-dicts
    a steep decrease with increasing IT. Combined with other two counterevidence previously
    reported, the IH-related effect is excluded from the origin of the shape elongation
    of metal NPs in SiO2."
