Spectroscopic Study of the 3107 cm−1 and 3143 cm−1 H-Related Defects in Type Ib Diamonds

Hydrogen-related infrared absorption bands in natural diamonds have been extensively investigated and widely used to identify natural, treated, synthetic grown by high pressure temperature (HPHT) chemical vapor deposition (CVD) techniques. However, the evolutional behavior of hydrogen-related defects relationship between nitrogen-related HPHT-treated Ib are unclear. In this article, defects, particularly 3107 cm−1 3143 type diamonds, were systematically using spectroscopic It was found that 1405 intensity directly proportional intensity; increased with increase intensity, but there no strict linear them. The band not only related also value NC/NA diamonds. When less than one, more pronounced. After high-temperature annealing, intensities became stronger. HPHT a defect introduced A centers difference detectability could be efficiently from their counterparts, including
