K2H(IOK3)2Cl单晶的喇曼光谱研究
Raman spectra of K2H(IOK3)2Cl crystals
摘要
本文报道了水溶液生长的K2H(IO3)2Cl单晶室温下喇曼光谱,有几条谱线的喇曼散射效率很高,说明该晶体可能作为喇曼频移器的材料,谱图中包含有氢键(O一H—O)的特征振动频率,在90°散射几何配置y(xx)z和z(yy)x下,观测到的A1(TO+LO)表示的谱图明显地不相同,晶体易遭受到光损伤。
Abstract
Raman spectra in K2H(IO3)2Cl crystals grown from aqueous solution at room temperature are reported. There are some spectral lines with very high Raman scattering efficiencies. This suggests that the crystal might be a good material as raman frequency shifter. The characteristic vibrational frequency of hydrogen bond (O-H-O) exhibits in the Raman spectra. Spectral patterns corresponding to the same representation A1(TO+LO) but obtained under different 90?scattering configurations y(xx)z and z(yy)x are obviously different. This kind of crystals is found to be vulnerable to damage by light.
