利用红外光谱法研究了球形SnO2纳米微粒的表面声子模特性,在实验上观察到了全部Frohlich模,并与理论计算结果进行了比较,讨论了空间量子限域效应对SnO2纳米微粒红外光谱特性的影响。The properties of the surface phonon modes in spherical SnO2 nanometer particles were studied by the method of infrared spectroscopy. The sum total of Frohlich modes of SnO2 nanometer particles were reported in our experiments. The theoretical results of surface mode frequency of SnO2 nanometer particles were presented, which agreed well with those of experiments. Finally, the effects of quantum confinement on the infrared properties of SnO2 nanometer particles were discussed.
