Structural and photoluminescence properties of Eu3+ doped α-Ag2WO4 synthesized by the green coprecipitation methodology

Abstract

Europium doped silver tungstates α-Ag_2−3xEu_xWO₄ (x = 0, 0.0025, 0.005, 0.0075 and 0.01 mol) were synthesized by the coprecipitation method at 90 °C for 30 minutes. PL spectra showed a broad band related to the [WO₆] group and characteristic narrow peaks due to the f–f transitions of Eu³⁺ as a result of efficient energy transfer from the matrix.
