The pump fluence dependent photoluminescence (PL) spectra of SnO 2 nanowires were investigated, which were synthesized with a high-temperature chemical reduction method. The integrated intensity of the narrower peak at 3.2 eV experiences a strong superlinear dependence on the pump fluence, and the n
