Abstract

The PL data bases reveal the fact that a part of lattice of HPHT treated diamond is 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 amount of nitrogen impurities is present in all of these type IIa diamonds, and reveal the presence of a considerable number of point defects dispersed throughout the crystal lattice.

PL data에 의해 다이아몬드가 HPHT(고온고압)으로 처리하는 과정을 거치면서 격자 내에 불순물 원자뿐만 아니라 공공과 침입형 원자의 움직임과 감소, 소멸, 생성 등으로 일부 격자가 재배열됨이 드러났다. 특히, PL spectrum은 Type IIa 다이아몬드가 가지는 매우 작은 양의 질소 불순물도 명확히 나타났으며, 이로 인해 상당한 수의 점결함이 결정 격자 내에 분산되어 있음을 알 수 있었다.
