Abstract
A characterization tool using synchrotron radiation as a light source to record excitation spectra of the visible luminescence of phosphors induced by photons in the V UV and UV range, at several temperatures (10 to 300 K), is developed. The absorption and deexcitation mechanisms in Y F{sub 3}, La F{sub 3} and Th F{sub 4} matrices doped with Eu{sup 3+}, Tb{sup 3+}, Dy{sup 3+} and Er{sup 3+} ions and polluted with oxygen ions, are examined; charge transfer bands appear clearly. The 4 f{sup n} to 4 f{sup n-1}5 d transition bands are also observed on the excitation spectra of the visible luminescence of these compounds and two processes are proposed to interpret the energy relaxation. In order to determine the candidates for the color plasma display panel, measurements of luminous and external quantum yields for efficient phosphors are carried out. The Y F{sub 3}:Eu{sup 3+} compound is shown as a good candidate for the red emission in color plasma display panels.
