Y. Mita et al., NEAR-INFRARED ABSORPTION-LINES IN NEUTRON-IRRADIATED AND ANNEALED SYNTHETIC TYPE IIA DIAMOND, Solid state communications, 102(9), 1997, pp. 659-661
Near-infrared absorption lines of 2916, 4066, 4113, 4139 and 4168 cm(-
1) have been observed in type IIa diamond neutron irradiated and annea
led at temperatures higher than 1400 degrees C. A photochromic behavio
ur of these defects under various illumination conditions is reported
and the phenomenon is explained by a charge transfer model. (C) 1997 E
