Understanding the structural and optical evolution of Eu3+ and Dy3+ co-doped YV...
Sekrafi, Houssem Eddine; Hergli, Eya; Ferdov, S.; Coutinho, Paulo J. G.; Rebouta, L.YVO4 nanoparticles co-doped with Eu3+ and Dy3+ ions were successfully synthesized using a conventional coprecipitation method. The resulting phosphors exhibited a single-phase trigonal YVO4 structure, with nanoparticles averaging approximately 60 nm in size, obtained by measurements carried out with scanning electron microscope images. UV–visible diffuse reflectance spectroscopy analysis reveals that the direct...
Optimization of photoluminescence of Eu<sup>3+</sup> doped YVO<inf>4</inf> nano...
Sekrafi, Houssem Eddine; Hergli, Eya; Ferdov, S.; Mota, André; Lopes, Joni; Coutinho, Paulo J. G.; Rebouta, L.A detailed investigation of the europium-doped yttrium orthovanadate (YVO4:Eu3+) phosphorus prepared by fast and facile microwave synthesis was undertaken. The phase purity, morphology, particle distribution analysis, and photoluminescence were all thoroughly examined. The photoluminescence (PL) properties of the as-synthesized YVO4:Eu3+ nanostructures depend greatly on the synthesis parameters. The PL intensit...
Layer formation, morphology and photoluminescent properties of ultrasonic spray...
Hergli, Eya; Sekrafi, Houssem Eddine; Ferdov, S.; Mota, André; Lopes, Joni; Coutinho, Paulo J. G.; Rebouta, L.In this work, we study the coating process and coating quality of photoluminescent particles deposited on a glass surface in terms of particle distribution and associated film continuity. The dispersion process of commercial ZnS:Mn particles and YVO4:Eu particles synthesized by microwave reactor in aqueous solutions onto solid surface was performed using an ultrasonic atomizer. Two methods of particle depositio...
