UV--vis Absorption and PL Properties of Self-Assembled Silicon Nanotubes
-
Abstract
Silicon nanotubes (SiNTs) are novel one-dimensional nanomaterials, which
have potential applications in nano-photoelectric 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 436nm are measured by UV--vis spectrometer and spectrofluorophotometer.
