無電極放電プラズマにおける蛍光体発光輝度と発光色に与える電子エネルギーの影響

摘要

The effects of electron energy distribution on light-emission luminance and on the luminescent color of phosphors in the light source were clarified. Inductively coupled discharge plasma was used as a promising electrodeless lamp for the light source. The light-emission luminance of the phosphors increased with the electron density in the plasma and/or the pressure of noble gas. The luminescent color was affected by the density of electrons with an energy of 5.0 or 6.7eV and by the visible light emission of the noble (Ne, Ar or Hg).
