摘　　要：采用激光拉曼光谱对各种颜色的淡水养殖珍珠和辐照改色淡水养殖珍珠进行了研究．发现了天然有色珍珠与辐照改色珍珠间的拉曼光谱的差异，据此建立了快速、无损鉴定改色淡水养殖珍珠的方法．Freshwater cultured pearls with natural colors and with radiation-color modification are studied by employing laser Raman spectrometry. Distinguished differences are found in the laser Raman spectrum between the pearls with natural colors and those with modified colors. Based on this finding, a rapid and non-destructive method for the identification of color-modified freshwater cultivated pearls is established.
