Europium-doped zinc formate was synthesized by crystallization from a solution prepared by the reaction of the diluted formic acid on a mixture of ZnO and Eu2O3, Zn1–x Eu x (HCOO)2+x ∙2H2O (0.005 ≤ x ≤ 0.05) under heating. Thermolysis of Zn1–x Eu x (HCOO)2+x ∙2H2O gave Zn1–x Eu x O1+x with no more than 2.5 at.% degree of replacement of zinc by europium. The influence of Eu3+ on the luminescent properties of the samples synthesized was studied by optical spectroscopy (IR, Raman, and UV visible and emission spectra).
