Synthesis of Eu³⁺-activated BaMoO₄ phosphors and their Judd-Ofelt analysis: Applications in lasers and white LEDs.

Eu(3+)-activated BaMoO4 phosphors were synthesized by the nitrate-citrate gel combustion method. The Rietveld refinement analysis confirmed that all the compounds were crystallized in the scheelite-type tetragonal structure with I41/a (No. 88) space group.

Facile synthesis of PbWO4: applications in photoluminescence and photocatalytic degradation of organic dyes under visible light.

Stolzite polymorph of PbWO4 catalyst was prepared by the facile room temperature precipitation method. Structural parameters were refined by the Rietveld analysis using powder X-ray data. PbWO4 was crystallized in the scheelite-type tetragonal structure with space group I41/a (No.
