Phosphor, Method for Manufacturing Same, and Particle Dispersed El Device Using Same

摘要

An EL phosphor contains a conductor phase including carbon nanotubes, carbon nanohorns, or another carbon component. The phosphor includes a sulfide that has Ag- or Cu-activated ZnS as a main component thereof. The phosphor includes material expressed by the general formula Zn(1-x)A_xS:Ag/Cu, D (where A is at least one type of group 2A element selected from the group consisting of Be, Mg, Ca, Sr, and Ba; D is a coactivator and is at least one element selected from the group consisting of group 3B or group 7B elements; and 0<=x<1), or an amorphous oxynitride phosphor comprising B-N-O, Si-O-N, Al-O-N, Ga-O-N, Al-Ga-O-N, In-Ga-O-N, or In-Al-O-N, which are activated by Eu²⁺, Gd³⁺, Yb²⁺, or another earth metal ion.
