Notes:
Infrared absorption and electron spin resonance measurements have been performed in nitrogen-containing mixed-type diamonds under several illumination conditions. It has been observed that bulk one-phonon absorption spectra are modulated by illumination of higher than 2.0 eV in photon energy and the change recovers within a few hours after the excitation light is turned off. The results are explained by the change in the charge state of isolated nitrogen, and a characteristic absorption band created by the positive charge state of isolated nitrogen (N+) is proposed. This phenomenon is applicable in decomposing the infrared absorption spectra of diamonds into each component, which contain information about the type and concentration of nitrogen aggregate. © 1998 American Institute of Physics.
