Abstract

Abstract: In the present work, Bi3 Ge4 O12 (BGO) was synthesized by the polymeric precursor method using different chelating agents. We present a comparative analysis of each chelate formation and how the physicochemical properties of the BGO were affected, specifically its luminescence. In this work we used citric acid (CTR), ethylenediaminetetraacetic acid (EDTA), ethylene glycol (EG), nitrilotriacetic acid (NTA) and tartaric acid (TA), since they are the most reported chelating agents for this type of synthesis. The BGO materials were characterized by scanning electron spectroscopy (SEM), X-ray diffraction (XRD), Fourier Transform infrared spectroscopy (FTIR) and photoluminescence (PL), and showed that the luminescence properties of the synthesized BGO was affected by the formation of secondary phases. The changes in the BGO luminescence properties with the use of each chelating agent are discussed. Graphical abstract: fx1 Highlights: This job presents the synthesis the Bi4 Ge3 O12 with different chelating agents. The polymeric precursor method was used to obtain pure phase of BGO. The BGO luminescence intensity can be tuned depending on the nature of chelating agent.
