从Raman光谱可以明显看出,随着煅烧温度的升高,Mn3O4/C复合材料逐渐转化成以Mn3O4为主,而随着原料中葡萄糖比例的增加,材料逐渐转化成以碳成分为主。根据材料活化PS前后的XPS谱图对比可以看出,反应后表层部分Mn的平均氧化态升高,表明Mn...

The room-temperature ferromagnetism is observed in Zn 0.98Mn 0.02O nanoparticles, which is related to the host-lattice defects induced by doping Mn. The ferromagnetism in Zn 0.95Mn 0.05O nanoparticles can be suppressed by Mn clusters. The additional peak at 519cm 1 is observed in Raman scatteri...
