Abstract
The quality, quantity, color, and characteristics were found out cultured seawater pearls and freshwater pearls. In the XRF measurement Ca chemical combinations were the main elements and Sr was detected at higher levels for the sea-water pearl and Si, S, Ca, Mn, P and other elements were found at higher levels for the fresh-water pearls. Such differences is judged to be caused by the ion diluted in sea and fresh water which affects the pearl elements. Although near similar structural peak was shown for the FT-IR measurement, the fresh-water pearl showed a lower peak for the 2344 wave. For the results of PL, the peak for fresh-water measured with Hd-Cd Laser at 455 nm was higher and with the Ar-ion Laser measurements, peaks were high at 545 nm and 570 nm for fresh-water pearl and sea-water pearls respectively.
양식된 해수진주와 담수진주의 품질, 수량, 색상 등과 특성을 알아보았다. XRF 측정에서는 Ca 화합물이 주성분이며 해수진주에서는 Sr이 담수진주는 Si, S, Ca, Mn, P 등의 원소가 더 많이 검출되었다. 이러한 차이는 해수와 담수에 녹아 있는 이온이 진주성분에 영향을 준 것으로 판단된다. FT-IR 측정에서 거의 동일한 구조적인 peak를 나타내지만 2344$\textrm {cm}^{-1}$에서 담수진주의 흡수대가 나타났다. 광원으로 He-Cd Laser 사용으로 455 nm에서 peak는 담수진주가 높았고, Ar Laser 사용으로 담수진주는 545 nm에서 해수진주는 570 nm에서의 peak가 높았다
