Silicon nanotubes (SiNTs) are novel one-dimensional nanomaterials, which have potential applications in nanophotoelectric devices, sensors and field-emission devices. The self-assembled silicon nanotubes have clear structures without metal catalysts. The structures are confirmed by TEM and HRTEM, and the UV-vis absorption spectra with an absorption peak near 685nm and PL spectra with widened strong emission near 436 nm are measured by UV-vis spectrometer and spectrofluorophotometer.
