Research on FT-IR-PAS Spectra of Nanocrystal ZrO2
单斜纳米ZrO2材料 傅里叶交换红外光声光谱(FT-IR-PAS) 量子尺寸效应 nanocrystalline monoclinic ZrO2 Fourier transform infrared photoacoustic spectros quantum size effect
摘要
首次报道单斜ZrO2纳米材料在各种微晶粒度下的傅里叶交换红外光声光谱(FT-IR-PAS)，发现随着粒度的减小，波数低于1048 cm-1的谱线强度减弱，而波数高于1048 cm-1的话线强度增加，一些话线位置有红移，并观察了压力效应.对上述量子效应进行初步解释.
Abstract
It is reported for the first time that Fourier transform infrared photoacoustic spectroscopy (FT-IR-PAS) spectra of nanocrystalline monoclinic ZrO2 with different particle size. The results show that absorption intensities of Peaks below 1048 cm-l decrease, while those above 1048 cm-l increase. The POsition of some Peaks have red shift as decrease of particle size. Primary explanation is made for these quantum effects. The pressure effect is also observed.
