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 ...
A fresh look at the structural, ferroelectric and photoluminescent properties in perovskites
(2012-12-01)
The perovskite based materials ABO3 are in huge expansion worldwide. Fundamental scientific studies on perovkite materials have been carried out intensively due to their unique dielectric, piezoelectric, and ferroelectric ...
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 ...
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 ...
Novel approaches of nanoceria with magnetic, photoluminescent, and gas-sensing properties
(ACS Publications, 2020-06-15)
The modification of CeO2 with rare-earth elements opens up a wide range of applications as biomedical devices using infrared emission as well as magnetic and gas-sensing devices, once the structural, morphological, ...
Experimental and theoretical studies of photoluminescence in Zns obtained by microwave-assisted solvothermal method
(2013)
A shift of the photoluminescence (PL) emission was observed in ZnS prepared by microwave assisted solvothermal method with the increase of the time in microwave. In this work we reported a study of the optical behavior ...
Effect of heat treatment on the generation of structural defects in LaTaO4 ceramics and their correlation with photoluminescent properties
(Elsevier B.V. Sa, 2011-09-15)
The synthesis, structure characterization, as well as luminescence properties of LaTaO4 ceramics were investigated in this study. The materials were prepared through the Pechini method. The characterization techniques, ...
Photoluminescent property of mechanically milled BaWO4 powder
(Elsevier B.V., 2007-10-01)
Crystalline BaWO4 (BWO) powder obtained by the polymeric precursor method was structurally disordered by means of high-energy mechanical milling. For the first time a strong and broad photoluminescence (PL) has been measured ...
