Preparation of polycrystalline samples of the EuLnCuS(3) (Ln = Gd, Lu) compounds

摘要

Polycrystalline samples of the EuLnCuS(3) (Ln = Gd, Lu) compounds have been synthesized at 1220 and 1370 K by reacting flowing H2(S) and CS2 with mixtures of micron- and nanometer-sized particles of rare-earth mixed oxides and cuprates. The mixtures have been prepared at 1270 K by the thermolysis of cocrystallized rare-earth and copper nitrates and aqueous metal nitrate solutions sprayed into a reactor.
