CdMoO 4 synthesized by a microwave-assisted hydrothermal method and their photoluminescence and photocatality properties
(2012-08-20)
In this work CdMoO 4 nanoparticles were obtained under hydrothermal conditions using microwave radiation (2.45 GHz) (MH) at 100°C for different times. These powders were analyzed by X-ray diffraction (XRD), Field-emisson ...

Enhancement of symmetry-induced photoluminescence in bismuth tungstate microcrystals
(2016-12-01)
Bi2WO6 (BWO) powders synthesized via hydrothermal processes were studied in order to determine the effect of structure on photoluminescence (PL). BWO samples were characterized using X-Ray Powder Diffraction, UV–vis diffuse ...
Structural and optical properties of soluble melanin analogues with enhanced photoluminescence quantum efficiency
(2018-05-01)
Melanin is a functional material of growing interest for bioelectronics. Several melanin analogues have been employed in order to fully explore its potential; in this work melanin was synthesized using dimethylsulfoxide ...
Photoluminescence in NaNbO3 particles and films
(Elsevier B.V., 2015-01-15)
In this work, we report the photoluminescence properties of NaNbO3 particles and films. The crystallization of NaNbO3 particles produced Na2NbO6.nH(2)O intermediate phase which was then converted to NaNbO3 following thermal ...
