Neutron-irradiation-induced near-infrared emission in α-Al2O3
Source abstract
Abstract
AbstractNear-infrared spectroscopic study of neutron-irradiated -AlO was conducted. Scanning-electron and optical microscopic measurements were also done. Sample irradiated to the fluence of shows strong emission band at 1180, 1700, 1945 and 2225 nm. Photoluminescence (PL) intensity of these bands reduced greatly with higher neutron fluences. From reduction of PL intensity, it can be reasonably assumed that nonradiative recombination centres such as extended defects or dislocations may be formed in -AlO after exposing to very high neutron fluences.Keywords: near-infrared spectroscopyneutron-irradiationlattice defectsdislocationsalumina AcknowledgmentsWe acknowledge Mr Zhaojing Wen of Beijing Chemical University and Keyence staff for their help with the SEM and OM experiments, respectively.Notes1 This work was partially supported by the NSFC [grant number 91026006] and Chinese Academy of Sciences Fellowships for Young International Scientists under [grant number 2012Y1JB0007].
