Abstract

A new phosphor material, SrS doped with both Pr and Ce, with bright white emission was proposed for an application to multi-color thin film electroluminescent (TFEL) devices. Spectral changes by varying a concentration ratio of the activators and color separation with filters for SrS:Pr,Ce TFEL cells were studied. It was shown that three primary colors with suitable color coordinates and with balanced luminance levels could be obtained by utilizing SrS:Pr,Ce phosphor layers and color filters.
