摘要	single crystalline -Si3N4 nanobelts synthesized via catalyst-assisted pyrolysis of polymeric precursor were investigated using absorption, photoluminescence (PL) and photoluminescent excitation (PLE). The optical absorption spectrum showed that the nanobelts exhibited indirect absorption behavior with optical band gap of [similar to] 5.0eV. Three broad peaks centered at 1.8eV, 2.3eV and 3.0eV were observed from PL spectrum of the nanobelts at room temperature. The PLE spectra suggest the existence of multi-fold energy levels within the gap.
