摘　　要：利用硒化锌微球表面的银镜反应制备了银/硒化锌(Ag/ZnSe)核壳结构微球,并利用扫描电镜(SEM)、X射线衍射(XRD)以及傅里叶变换红外光谱仪对其进行了表征,研究了Ag/ZnSe核壳结构对硝酸钠水溶液红外吸收光谱特性的影响。结果表明,Ag/ZnSe核壳结构微球使得硝酸钠反对称伸缩振动模式频率发生了明显的蓝移,振动强度有了较大程度的提高。Silver/zinc selenide （Ag/ZnSe） core-shell structure spheres were made through the method of silver mirror reaction on zinc selenide micro spheres. Surface morphology of the spheres was depicted by scanning electron microscopy, X-ray diffraction and Fourier infrared absorption spectrum. This paper studies the effect of Ag/ZnSe core-shell structure spheres on the infrared absorption properties of sodium nitrate solution. The results show that, the anti-symmetric vibration absorption peaks of nitrate are blue-shifted, and the intensity are improved obviously by the effect of core-shell structure spheres.
