Abstract

  In the field of nuclear fusion technology, Er₂O₃ thin film is a candidate for the coating material of the blanket of thermonuclear fusion reactor. It is known that the luminescence of Er₂O₃ provides information on its crystallinity. We observed luminescence of Er₂O₃ during the irradiation with highly charged ions produced by an electron beam ion source (EBIS) as a function of charge state and kinetic energy of incident Ar ions. We found that the luminescence intensity non-linearly rises as the charge state increases and is independent of kinetic energy. This demonstrates that the luminescence of Er₂O₃ thin film arises from the potential energy of highly charged ions rather than the kinetic energy.<br>
