Synthesis, Characterization, Anisotropic Growth and Photoluminescence of BaWO4
(Amer Chemical Soc, 2009-02-01)
This paper reports on the synthesis of barium tungstate (BaWO4) powders obtained by the coprecipitation method and processed in a domestic microwave-hydrothermal (MH) at 413 K for different times. These powders were analyzed ...
Structure, Morphology, and Optical Properties of (Cal(1-3x)Eu(2x)) WO4 Microcrystals
(Korean Inst Metals Materials, 2015-03-01)
In this letter, we report the efficient, surfactant-free, microwave-hydrothermal method of synthesizing calcium europium tungstate [(Ca1-3XEu2X) WO4, x= 0, 0.05, 0.01, 0.02, and 0.04] microcrystals. The structure and ...
Estudo espectroscópico do íon Eu3+ dopado na matriz de tungstato de estrôncio obtido através do processo sol-gel não-hidrolítico
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2012-10-30)
In this work it was investigated the influence of the temperature, time of heat treatment, and the variation of the Eu3+ concentration into the SrWO4 framework related to their structural, morphological and photoluminescent ...
Estudo das propriedades fotoluminescentes dos compósitos de MgMoO4:SrMoO4 e ZnWO4:CaWO4 obtidos pelo método de spray pirólise ultrassônico
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2022-05-20)
Molybdates and tungstates are inorganic materials with immense potential in
application as white light-emitting diodes (wLEDs), which are an alternative to traditional
lighting sources. In this study, the synthesis and ...
Preparação de tunsgstatos cerâmicos do tipo scheelita com propriedades luminescentes
(Universidade Federal do Rio Grande do NorteBrasilUFRNPrograma de Pós-graduação em Ciência e Engenharia de MateriaisCentro de Ciências Exatas e da Terra, 2002)
The development of materiais with optical properties is of great technological importance. In crystalline form, AWO4 tungstates (A = Ca, Sr, Ba and Pb) are insulating materiais with high energy gap and great commercial ...
