During the last years, the scientific and industrial community has focused on the astonishing properties of Fe–Mn–Al–C steels. These high advanced steels allow high-density reductions about ~ 18% lighter than conventional steels, high corrosion resistance, high strength (ultimate tensile strength...

在Mn摩尔分数从0增加到5.6%的过程中,ZnO:Mn薄膜始终保持着六角纤锌矿结构;随着Mn掺杂浓度的增大,437 cm-1和527 cm-1位置上的Raman散射峰出现红移现象,说明Mn掺杂量的增加导致晶格更加无序,缺陷增多;当Mn摩尔分数达到15.8%时,647 cm-1处的Raman散射峰出现,暗示了MnO的产生,同时薄膜结晶质量变差.这一结论也得到...

A Raman band at 571 cm-1 corresponding to the nu(s)(Mn-O) vibration is very strongly enhanced in intensity by resonance with this electronic transition. It points to a very strong pi-delocalization within the Mn(DBQ)+ chelate ring, which is probably also the main factor responsible for ...
