| 摘 要： | 通过显微镜、紫外荧光、阴极发光特征的观察和拉曼光谱分析,对塔希提黑珍珠、γ射线辐照淡水养殖珍珠、不同工艺染色的淡水养殖黑珍珠和染色加辐照黑珍珠这4种黑色珍珠的特征进行了对比研究.结果表明:塔希提黑珍珠在长波紫外灯下可发暗红棕色荧光,短波紫外灯和阴极射线下不发光,拉曼光谱可见文石和有机卟啉峰;辐照处理淡水养殖珍珠和染色加辐照处理淡水养殖珍珠在长波紫外灯下和阴极射线下均发强绿色光,且能观察到不同程度的表面破损和内部龟裂纹,拉曼光谱只可见文石的谱峰;染色淡水养殖黑珍珠在紫外灯下荧光不强,在阴极射线下发黄绿色光,可见表面破损.

| Abstract: | The characteristics of Tahiti pearls,irradiated freshwater cultured pearls,black dyed freshwater cultured pearls and irradiated dyed-pearls are examined by microscope,uv fluorescence,cathode luminescence microscope and Raman spectroscopy.Tahiti pearls show dark brownish red in ultra-wave fluorescence,aragonite and porphyrin peaks in Raman spectra,while two kinds of irradiated pearls show strong green and only aragonite peaks.In cathode luminescence microscope,irradiated pearls appear strong green and dyed pearls present yellowish green with emerging different level surface breach. |
