摘要
采用中红外(MIR)光谱技术研究玻璃镜片气泡结构,发现气泡结构的红外吸收模式主要为νasO=C=O-一维。采用变温中红外(MIR)光谱进一步研究了气泡结构的热稳定性,发现在303~393 K范围内的主要官能团(νH-O-H-一维、νasO=C=O-一维和δO=C=O-一维)的吸收频率及强度发生变化。采用二维MIR光谱深入研究了主要官能团(νH-O-H-二维、νasO=C=O-二维、δH-O-H-二维、νsO=C=O-二维、δO=C=O-二维)对热的敏感程度及变化快慢,发现玻璃镜片气泡结构红外吸收模式主要集中在3420~3380 cm^(-1)、2365~2335 cm^(-1)、1660~1630 cm^(-1)、1350~1330 cm^(-1)及680~660 cm^(-1)5个频率区间,在这5个区间内展现出不同的光谱性能。本工作拓展了三级MIR光谱(包括MIR光谱、变温MIR光谱和二维MIR光谱)研究在重要的光学产品(如玻璃镜片)中气泡结构及热变性的范围。
The bubble structure of glass lenses had been studied by middle infrared(MIR)spectroscopy.The infrared absorption modes of bubble structure of glass lenses mainly includeνasO=C=O-one dimension.The thermal stability of bubble structure of glass lenses was further studied by temperature varying MIR spectroscopy.It was found that the main functional groups(νH-O-H-one dimension、νasO=C=O-one dimension andδO=C=O-one dimension)absorption frequency and intensity of the bubble structure of glass lenses had changes in the temperature range of 303~393 K.The main functional groups(νH-O-H-two dimension,νasO=C=O-two dimension,δH-O-H-two dimension,νs O=C=O-two dimension andδO=C=O-two dimension)information about the sensitivity to heat and the change speed of bubble structure of glass lenses were further studied by two-dimensional MIR spectroscopy.It is found that the infrared absorption modes of glass lens bubble structure are mainly concentrated in 3420~3380 cm^(-1),2365~2335 cm^(-1),1660~1630 cm^(-1),1350~1330 cm^(-1)and 680~660 cm^(-1),about 5 frequency ranges,which show different spectral performance.This paper had expanded the research scope of three-stage MIR spectrum(including MIR spectrum,variable temperature MIR spectrum and two-dimensional MIR spectrum)in the bubble structure and thermal denaturation of important optical products(glass lenses).
