Helium plasma irradiation to metals leads to morphology changes in nanometer scales by the formation of helium bubbles. The nanostructure significantly alters the optical property of the metal. In this study, near infrared radiations from a heated nanostructured tungsten are measured with a spectrometer. Energy balance between the influx of plasma and radiation from the sample is discussed in terms of the optical emittance. It is shown that the optical emittance is increased considerably by the morphology change in the range from visible to near infrared, and the efficiency of radiation is increased by two to three times.
