摘要
在这项工作中，我们报道了用高剂量的电子辐照NbSe2形成的NbSe2(二硒化铌)纳米管的生产。辐照装置为2 MeV Van de Graaff加速器，辐照条件为:电压1.3 MeV，电流5 μA，剂量率25 kGy/min，总剂量1000 kGy。当辐照剂量在100、250和500毫微克之间变化时，这些条件保持不变。我们观察到长几纳米，宽几纳米的巨大且非常清晰的纳米管，它们是中空的，一端有盖子。当辐照量增加到500mrad时，观察到洋葱状结构。
EFFECT OF ELECTRONIC IRRADIATION IN THE PRODUCTION OF NbSe2 NANOTUBES
In this work, we report the production of NbSe2 (niobium diselenide) nanotubes formed by irradiating NbSe2 with high doses of electron irradiation. The apparatus used for the irradiation was a 2 MeV Van de Graaff accelerator at the following conditions: voltage 1.3 MeV, current 5 μA, dose rate 25 kGy/min, and total dosage 1000 kGy. These conditions were maintained fixed while irradiation dosage was changed between 100, 250 and 500 Mrad. We observed enormous and very well defined nanotubes with a length of several nm and width of a few nm, which are hollow and capped at one end. As the level of irradiation is increased to 500 Mrad, onion-like structures were observed.
