摘    要:利用显微拉曼技术对手指沾有微量毒品--走私海洛因做了测试分析,在可见光514.5nm激发下,低浓度的走私海洛因具有很强的荧光,通过对样品表面的分析,得到了高质量的海洛因拉曼散射谱。研究表明选取样品表面合适测试点和控制激光功率对减小走私海洛因拉曼散射谱的荧光有明显的作用。

关 键 词:海洛因  显微拉曼技术  可见光激发  毒品走私  毒品分析

Abstract:Under incident light 514 5 nm,Raman scattering spectrum of trace contraband Heroin on finger with low concentration was investigated.It has been known that contraband Heroin has strong fluorescence background in its Raman scattering under visible excitation.By analyzing the sample surface and applying appropriate experimental method,the high signal noise ratio quality and low fluorescence Raman spectrum was obtained.The result indicated that it would be much improved the Raman scattering spectrum by using slick Al slice as gasket for drugs and selecting proper area on the sample surface,controlling the incident light power.This work could provide a powerful method for detecting trace materials including drugs,explosives,deleterious material in forensic science.
Keywords:Micro Raman  Trace contraband Heroin  Visible light excitation
