| 简介 |
The present invention provides an EL phosphor in which the phosphor contains a conductor phase including carbon nanotubes, carbon nanohorns, or another carbon component. The phosphor containing a conductor phase is a sulfide that has Ag- or Cu-activated ZnS as a main component thereof. In particular, the present invention provides a phosphor expressed by the general formula Zn(1-x) A x S : 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 Eu 2+ , Gd 3+ , Yb 2+ , or another earth metal ion. A surface light emitter manufactured using this phosphor has a conductor phase present therein, and thereby provides a particle-dispersed EL device for emitting high-intensity UV rays or nearby visible light when excited by an electric field. |
