Abstract

Copper concentration gradient in commercial SSR-ZnS:Cu, Al particles was calculated. Phosphor particles were etched by hydrochloric acid. The average copper concentration was measured by inductively coupled plasma spectroscopy (ICP). The surface copper concentration was estimated by the x-ray photoelectron spectroscopy (XPS). The concentration effect of copper on the luminescent intensity was specified by a coefficient.
