| 摘 要： | 以不同粒度的纳米氧化镁为研究对象,通过XRD,IR等测试手段对样品进行表征,针对纳米氧化镁的红外吸波性能进行研究.红外光谱分析结果表明:在400～600 cm-1的范围内吸收峰宽化,红外吸收能力显著增强;纳米氧化镁红外吸收域红移、蓝移共存,随着粒径的减小IR光谱先发生蓝移,当粒径在50 nm附近时出现拐点,发生红移.晶体场效应往往导致吸收峰的宽化,这是由于纳米微晶的"表面原子效应".纳米粒子粒径的减小会导致原来常规块体材料的谱带精细结构消失,从而形成宽而平的吸收带.

| Abstract: | MgO with different nanoparticle sizes were prepared and their samples were characterized by XRD and IR spectroscopy to investigate their infrared wave absorptivities.IR spectroscopic results indicated that the absorption peak widens in the range from 400 to 600 cm-1 and the IR wave absorptivity is improved evidently,where red shift and blue shift coexist.The blue shift is found with the decreasing particle size,then the red shift is found when an inflection point takes place in the vicinity that the particl... |
