PL을 이용한 HPHT 처리된 다이아몬드 감별에 관한 연구

Identification of HPHT Treated Diamonds using Photoluminescence

The PL data bases reveal the fact that a part of lattice of HPHT treated diamonds were reconfigured by the reduction, elimination, generation, and movement of vacancies and interstitials, as well as of impurity elements. In particular, this very sensitive method clearly illustrated that minute amounts of nitrogen impurities are present in all of these type II a diamonds, and reveal the presence of a considerable number of point defects was dispersed throughout the crystal lattice.
