A novel approach to obtain highly intense self-activated photoluminescence emissions in hydroxyapatite nanoparticles
Machado, Thales Rafael; Sczancoski, Júlio César; Beltrán Mir, Héctor; Costa Nogueira, Içamira; Siu Li, Maximo; Andres, Juan; Cordoncillo, Eloisa; Longo, Elson Elsevier (2017-05)Defect-related photoluminescence (PL) in materials have attracted interest for applications including near ultraviolet (NUV) excitable light-emitting diodes and in biomedical field. In this paper, hydroxyapatite [Ca10(PO4)6(OH)2] ... -
Effects of chemical substitution on the structural and optical properties of α-Ag 2− 2x Ni x WO 4 (0≤ x≤ 0.08) solid solutions.
Da Silva Pereira, Wyllamanney; Meneghetti Ferrer, Mateus; Botelho, Gleice; Gracia, Lourdes; Costa Nogueira, Içamira; Pinatti, Ivo M; Rosa, Ieda; de Almeida La Porta, Felipe; Andres, Juan; Longo, Elson Royal Society of Chemistry (2016)In this work, we investigated the effects of chemical substitution on the structural, electronic, and optical properties of α-Ag2−2xNixWO4 (0 ≤ x ≤ 0.08) solid solutions prepared by a facile microwave-assisted hydrothermal ... -
Synthesis and morphological transformation of BaWO4 crystals: Experimental and theoretical insights
Carvalho de Oliveira, Marisa; Gracia, Lourdes; Costa Nogueira, Içamira; Do Carmo Gurgel, Maria Fernanda; Rivas Mercury, José Manuel; Longo, Elson; Andres, Juan Elsevier (2016)BaWO4 crystals have been obtained by a co-precipitation method, and their structures were characterized by X-ray diffraction and Rietveld refinement techniques, while field emission scanning electron microscopy was utilized ...
