| 摘 要： | 通过紫外-可见(ultraviolet-visible, UV-VIS)吸收光谱、场发射扫描电镜(field emissionscanning electron microscope, FE-SEM)与傅里叶变换红外(Fourier transform infrared,FTIR)光谱对海水养殖金色珍珠(golden seawater cultured pearl, gold CP)的微结构及其吸收光谱特征进行了较系统的研究. 结果表明: 海水养殖金色珍珠外表面珍珠层“叠瓦状”结构的疏密程度在其表面的不同区域存在不同, 该特征可能是导致金色珍珠不同区域的紫外-可见吸收光谱存在差异的因素之一; 在由内向外的方向上, 接近珍珠核心处的珍珠层中未见单一的文石板片或棱柱结构, 而在珍珠层的中部及外侧区域均为文石板片结构; 珍珠层的外表面由多级结构构成, 其中单个珍珠层微米级的文石板片由纳米级文石小颗粒组成.

| Abstract: | A systematic study on the golden seawater cultured pearl (gold CP) were carried out using ultraviolet-visible (UV-VIS) absorption spectrum, field emission scanning electron microscope (FE-SEM) and Fourier transform infrared (FTIR) spectra. The following results were obtained. Density of imbricate structure on the surface of gold CP is different, maybe a result of the slight varied UV-VIS absorption spectrum. From inside to outside of nacreous layer in the cross-section, aragonite sheet or prism structure has not been found in the region near the nucleus. In contrast, aragonite crystal exists in a form of sheet structure in the middle and the outer part of the nacreous layer. The surface of nacreous layer displays the characteristic of multistage structural units, and a micro-sheet existing in the surface of nacreous layer is composed of many aragonite nano-particles. |
