摘　　要：通过阴极发光仪对养殖珍珠和处理养殖珍珠的阴极发光特征进行了研究,结果表明:在阴极射线激发下,淡水养殖和处理珍珠发黄绿或绿色光,而各色海水养殖和处理珍珠不发光;阴极显微观察可见部分处理珍珠层的表面微破损。淡水珍珠和海水珍珠不同的发光特点与其所含的微量过渡元素有关:淡水珍珠因富Mn而发光,海水珍珠则由于贫Mn富Sr而不发光。阴极发光特征可作为无损鉴别海水、淡水养殖珍珠以及处理养殖珍珠的主要依据之一。Characteristics of cultured pearls and treated pearls are studied by cathode luminescence microscope. In cathode luminescence microscope, freshwater cultured pearls and treated cultured pearls show yellow-green or green because of Mn, while other seawater cultured pearls present none fluorescence due to Sr. The characteristic cathode luminescence is one of the peculiarities to distinguish freshwater cultured pearls, seawater cultured pearls and treated pearls.
