摘　　要：紫外可见光谱分析是鉴定珠宝玉石的常规项目,目前合成祖母绿主要通过包裹体特征与红外吸收光谱特征进行鉴定;然而,合成祖母绿的紫外可见吸收光谱也具有一定的鉴定意义。文章中采用的测量仪器,是以微型光纤光谱仪作为核心检测器,基于反射测量的光谱分析仪,通过测量分析几种市场上常见合成祖母绿在紫外可见光纤光谱仪下呈现的光谱特征,旨在表明紫外可见光纤光谱仪在鉴定合成祖母绿应用中的可行性与重要性。各种仪器的互相鉴证有利于防范未知的检测风险,进一步提高鉴定结论的准确性。UV-Vis spectrum analysis is a routine item to identify gems. At present, synthetic emerald is mainly identified by inclusion characteristics and infrared absorption spectrum characteristics. However, the UV-Vis absorption spectrum of synthetic emerald has also a certain identification significance. The measuring instrument used in this paper takes the micro-optical fiber spectrometer as the key detector and the spectral analyzer based on reflection measurement to analyze the spectral characteristics of several common synthetic emeralds in the market under the UV-vis optical fiber spectrometer in order to show the feasibility and importance of the UV-vis optical fiber spectrometer in the application of identifying synthetic emeralds. The mutual authentication of various instruments is conducive to prevent unknown detection risks and to further improve the accuracy of identification conclusion.
