열처리에 따른 합성과 천연 에메랄드의 분광특성분석

국문 초록 (Abstract)

합성과 천연 에메랄드의 열처리에 따른 분광특성 변화를 가시광선과 적외선 분광분석으로 관찰하였 다. X-선 형광분석 결과 flux 합성 에메랄드에서는 Mo과 Co이 검출 되었고, hydrothermal 합성 에메랄드에서 는 Cl 성분이 나타났다. 자외선-가시광선 분광분석 결과는 콜롬비아산 에메랄드 시료에서 열처리 후에 전체적 인 흡수 세기가 증가 한 것을 확인 하였다. 적외선 분광 분석 결과, hydrothermal 합성 에메랄드에서 Cl 성분 에 관련된 피크가 3000-2600cm -1에서 나타났고, 천연 에메랄드에서는 CO₂에 기인하는 2358cm -1피크가 열처리 후에 감소된 것을 확인하였다. 이는 열처리 후에 기체 성분이 변화된 것과 일치 하였다.

The spectroscopic characteristics of synthetic and natural emeralds were investigated by UV-Vis and FTIR spectroscopy before and after heat treatment. The Mo and Co for synthetic flux and Cl for synthetic hydrothermal emeralds have been detected by X-ray fluorescence analysis. In the region of UV-Visible, the absorption of emerald from Colombia was generally increased after the heat treatment. The peak which related to Cl component in the 3000-2600cm -1 was shown in the hydrothermal synthetic emeralds by FTIR spectroscopy. The 2358cm -1 peak which originates from CO₂ was decreased after the heat treatment in the natural emerald. This was corresponded with the changes of gas element after heat treatment.
