| 摘 要： | 采用射频等离子体化学汽相沉积法得到了类金刚石（以下简称DLC）薄膜,并用能量为14MeV的中子对其进行辐照,辐照剂量为1.4×1012n/cm2～7.2×1012n/cm2。通过Raman及红外光谱分析得出,中子辐照造成膜中SP3C-C键的明显减少及SP2C=C键的增加,并形成少见的非晶型SP1C≡C键碳（直线型碳）,使DLC膜进一步非晶化。经辐照后的DLC薄膜红外透过率均有所提高,在实验剂量范围内,基本上与辐照剂量无关。 |
| 关 键 词： | 类金刚石薄膜 中子辐照 光谱 SP3C-C和SP2C-C键 |

| Abstract: | Diamond-like carbon(DLC)film, prepared by rf PCVD, was irradiated by 14 MeV neutrons up to 10 n/cm . The Raman and infra-red (IR) spectroscopy measurements showed that the SP3C-H and SP C=C bonds were decreased and increased, respectively. The neutron irradiation leads to the appearance of amorphous SP C=C (straight line carbon)bonds. The IR transmittance of DLC films is increasing, and independent of the irradiation doses in the experiments. |
| Keywords: | diamond-like film neutron irradiation spectroscopy SP3C-H and SP2C-C bonds |
