 note = {0000-0001-8616-6041, Fiberform nanostructured tungsten (FN-W) samples were synthesized by helium plasma irradiation with different irradiation times. It is shown that the optical reflectivity decreases significantly with the increase of the irradiation time, even in a long-wavelength infrared range up to several dozen µm. These experimental results are of importance for the usage of retroflectors and will offer a promising direction for other practical applications.},
