A facile reduction of Eu3+ to Eu2+ in gadolinium monosulfide nanoparticles using a mixed solvent of oleic acid/hexadecylamine.


PMID 22139447

Abstract

We prepared GdS:Eu(3+) by simple thermal decomposition under 1-dodecanethiol. A reduction process was observed from Eu(3+) to Eu(2+) when oleic acid and hexadecylamine were injected into GdS:Eu(3+). Under UV excitation, GdS:Eu(3+) showed an intense orange-red emission and GdS:Eu(2+) showed a broad green band.
