Abstract

We prepared GdS:Eu³⁺ by simple thermal decomposition under 1-dodecanethiol. A reduction process was observed from Eu³⁺ to Eu²⁺ when oleic acid and hexadecylamine were injected into GdS:Eu³⁺. Under UV excitation, GdS:Eu³⁺ showed an intense orange-red emission and GdS:Eu²⁺ showed a broad green band.
