TGS类铁电晶体的红外反射光谱研究
Study of infrared reflection spectra of TGS-family ferroelectric crystals
【摘要】 本文研究了室温下TGS类铁电晶体(包括TGS、DTGS和ATGSP晶体)的红外反射光谱,并将观察到的谱线按照频率和振动模式列表和分类.在ATGSP的红外光谱中发现存在PO43-离子的930cm-1谱线,说明磷酸取代硫酸进入晶相.
【Abstract】 Infrared reflection spectra at room temperature have been investigated for TGS-family ferroelectric crystals, including TGS. DTGS and ATGSP. The observed lines are tabled and classified according to their wavenumber and modes. We have found that there is a line at 930cm-1 resnlting from PO43--ions group on the infrared spectra of ATGSP. This indicates that the phosphoric acid enters the crystal, replacing sulphuric acid.
