天然水晶和水热法合成水晶的拉曼光谱分析

水热法合成水晶是依据天然水晶的物理化学性质并模拟其形成环境制得,常规检测方法无法鉴别。本论文采用法国(HORIBA Jobin Yvon)OLYMPUS BX41激光拉曼仪测试分析,并对天然水晶与水热法合成水晶拉曼谱466 cm~(-1)谱峰进行高斯线性拟合,发现水晶半高宽均大于6.5 cm~(-1),而合成水晶半高宽均小于6.5 cm~(-1)。拉曼光谱半高宽值的差异可对天然水晶和水热法合成水晶的鉴别提供依据。

Study on Raman Spectrum of Natural Crystal and Synthetic Crystal by Hydrothermal Method

Synthetic crystal by hydrothermal method is based on the physical and chemical properties of natural crystal which can simulate the formation environment,conventional detection methods can't be identified.This paper used the laser Raman spectrometer of French Olympus BX41 to test,the natural crystal and synthetic crystal of Raman spectrum 466 cm-1 spectra were fitted by linear Gaussian fitting,it found that the FWHM of nature crystal were more than 6.5 cm-1,the FWHM of synthetic crystal were less than 6.5 cm-1.The Differences of Raman FWHM can provide the information to identify the natural crystal and synthetic crystal by hydrothermal method.
