摘要：The technique of micro-Raman spectroscopy has the advantages of being nondestructive, high speed, high accuracy and also can be used for finite-precision analysis in combination with microscopy. In this paper, bleached and filled jadeite-jade and filled ruby were selected as the analysis objects, and then micro-Raman spectroscopy in combination with XRF and IR was carried out for detection and analyses. There were many microcracks observed in the micrograph of jadeite-jade, which is the result of bleaching with strong acid, and it was proved that these cracks were filled with epoxy resin by the diagnostic Raman shifts near 777, 1123, 1611, 2930, and 3065cm-1. Many cracks and white floccules were observed in the micrograph of filled ruby; This was the result of filling with lead glass and organic material. In addition, the broad and strong Raman shift near 1563cm-1 was attributed to lead glass, and Raman shifts near 2331, 2874, and 3285cm-1 were attributed to organic filler. This analysis method also can be applied for identification of other varieties of filled gemstones.
