Abstract

original image

Adopting the concept of one dopant for one color, all the prominent emitting colors in the visible windows are obtained by doping selective dopants (Ag, Cu, Ni, and Cu) in an appropriate host (alloy of CdxZn1-xS) with fixed size/composition and bandgap. Analyzing the origin of these emissions the relative position of respective dopant states are correlated.
