摘要：

SnO2 nanowires (NWs) have been successfully synthesized on two different substrates (stainless steel (SS) and copper) via a facile hydrothermal process. SnO2 NWs with varying degrees of crystallinity are obtained on different substrates. The growth mechanisms are also deducted by observing the morphology revolution at various reaction times. Furthermore, the electronic structures and optical properties have been investigated by X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) measurements. The yellow-green luminescence from SnO2 NWs is originated from the intrinsic surface states. Compared with SnO2 NWs on copper, a near infrared (NIR) luminescence is observed for SnO2 NWs on SS, which resulted from poor crystallinity and an abundance of defect/surface states.
