摘要
为探索优良非线性光学玻璃材料,研究了不同磷族元素掺入对GeS2–Ga2S3玻璃结构和性能的影响。利用传统的熔融淬冷技术,制备了0.8GeS2·0.1Ga2S3·0.1X2S3(X=P,As,Sb)3种硫系玻璃。差热分析表明:所制备的3种硫系玻璃的晶化温度和转变温度之差均大于100K,具有较好的成玻性能。Raman光谱、远红外光谱、可见–近红外光谱、Maker条纹等方法对3种硫系玻璃的结构和性能进行了分析。结果表明:玻璃内部存在较多的多面体单元可以导致玻璃在热电极化后出现较大的二阶非线性光学性能,玻璃在可见光波段透过率的不同将会导致在Maker条纹仪记录倍频光强度时出现反射和透射的倍频效应。
To find new excellent nonlinear optical glassy materials, evolution of structure and properties of GeS2 -Ga2S3 chalcogenide glasses doped with different pnicogen elements were investigated. Utilizing conventional melt-quenching method, the chalcogenide glasses 0.8GeS2,0.1Ga2S3-0.1X2S3 （X=P, As, Sb） were prepared. According to differential scanning calorimetry analysis, the diffe- rence between the glass crystallization temperature and the glass transformation temperature is larger than 100 K indicating their high glass-forming ability. Based on the analysis on the structure and properties of three chacogenide glasses by Raman spectra, far infrared spectra, visible-near infrared spectra and Maker fringe measurements. The results show that the more polyhedron units exist in the glasses can lead to larger second-order non-linear optical properties after the thermal-electric poling. The different transmissivity of the glass in the visible light region will lead to the appearance of transmitting and reflecting second harmonic generation（SHG） while record the SHG intensity in Maker fringe measurement.
