摘要

用10/sup 19/ cm/sup -2/的中子辐照温度为330 ~ 340 K后，研究了氮缺陷浓度约为10/sup 20/ cm/sup -3/的天然金刚石。在1200 ~ 1800 cm/sup -1/区域用10 min、50 K步长等时退火方法研究了详细的热扰动。由于氧化发生，温度上限为850 K。在每个退火步骤后对光谱进行了重新检查。照射后晶体立即完全变黑，因此无法记录或确定GR1中心的浓度。第一批出现的线条是1530和1370 cm/sup -1/。

FTIR spectroscopy of annealing processes in neutron irradiated diamonds

Natural diamonds with nitrogen defects at a concentration of about 10/sup 20/ cm/sup -3/ were investigated after irradiation by neutrons at a temperature of 330-340 K at a dose of 10/sup 19/ cm/sup -2/. Detailed thermal perturbations in the 1200-1800 cm/sup -1/ region were investigated by isochronal annealing with 10 min and 50 K steps. The upper temperature limit was 850 K because of oxidation onset. The spectra were rexamined after each annealing step. Immediately after irradiation the crystals were absolutely black, making it impossible to register or determine the GR1 centers concentrations. The first lines to appear were at 1530 and 1370 cm/sup -1/.
