Abstract
This paper primarily addresses various methodologies for synthesizing novel phosphors, with our focus mainly on the mixed alkaline tungstate phosphor Ca2MgWO6. In the initial synthesis phase, we used precisely weighed CaCO3, MgO, and WO3 for the synthesis. The XRD patterns indicated the presence of an impure phase, specifically CaWO4, in the resulting product. We adeptly tackled the formation of CaWO4 and mitigated it by employing a multifaceted approach. These included adding an excess amount of MgO, opting for an alternative chemical route, and the incorporation of flux during synthesis. It was observed that the product obtained through the addition of flux exhibited a purity level of approximately 99.75 with a margin of error of ± 0.02. Ultimately, we have carried out structural, morphological, optical, and thermal characterizations, along with density functional theory (DFT) simulations, to assess the fundamental parameters of the pure sample. © The Author(s) 2024.
