Abstract
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 intensity of the nanomaterials increased when the Eu concentration, holding time, and amount of water used in the prepared phosphors were adjusted. The optimal europium doping concentration was 7 mol% for temperature holding times of 60 min, and 5 ml of water was used as the solvent. The emission intensity of Eu3+-doped YVO4 phosphors can be rationally modified by simply changing the pH of the solution or by employing different solvents. The phosphors studied were produced as nanoparticles with a very intense emission spectrum, making them good candidates for fluorescent lamps and light-emitting diodes (LEDs).
