摘要: Abstract The mechanical stability of single-wall carbon nanotubes (SWCNTs) at high pressure was studied by high-resolution resonant Raman and wavelength-dependent fluorescence-excitation (PLE) spectroscopy resolving the vibrational electronic resonances 18 individual chiralities furthermore even different behaviour empty (closed, pristine) water-filled (opened) SWCNTs (diameter range = 0.6–1.42 nm). We find that water-filling exerts a stabilizing counter-pressure on SWCNT walls, leading to an increasing difference between radial breathing mode frequencies elevated pressures. For small diameter (d
