Silica glasses containing both ZnS quantum dots (QDs) and luminescent lanthanide ions are attractive candidates to develop new lighting displays, sensor devices or laser emitters. This work reports an easy sol–gel method prepare Eu3+-doped Eu3+,Mn2+-codoped nanocrystals dispersed in a transparent silica matrix. Semiconductor with average size of 5–6 nm exhibiting cubic hexagonal phases were obtained at low temperature. The interactions between QDs, Eu3+ Mn2+ provided materials different...
Eu3+-Doped CdS hexagonal nanocrystals (NCs), with an average size of ∼4 nm, have been prepared through a simple methodology based on the direct precipitation NCs using 1-thioglycerol as capping molecule. Steady-state and time-resolved photoluminescence studies (14–300 K) reveal effective NCs-to-Eu3+ energy transfer process involving surface localized states mediated by thermally activated exchange mechanism. Furthermore, analysis optical data also points out presence two distinct Eu3+ local...
Materials doped with the luminescent Eu3+ ion are attracting an ever-increasing amount of attention due to their potential applications in solid-state lighting, display devices, solar cells, or bioanalytics. But, why Eu3+? Unlike other lanthanides, its electronic features make calculation some physicochemical parameters quite straightforward, since they can be extracted directly from emission spectrum. Highly appreciated for reddish emission, has also been widely used as a site-sensitive...

In recent years, complex nanocomposites formed by Ag nanoparticles coupled to an α-Ag2WO4 semiconductor network have emerged as promising bactericides, where the attracts bacterial agents and neutralize them. However, production rate of such materials has been limited transmission electron microscope processing, making it difficult cross barrier from basic research real applications. The interaction between pulsed laser radiation revealed a new processing alternative scale up nanocomposite...
In this work, a series of BaxMn0.7Cu0.3O3 samples (x: 1, 0.9, 0.8, and 0.7, BxMC) was synthesized, characterized, used as catalysts for CO oxidation reaction. All formulations were active in the tested conditions. A correlation between electrical conductivity, obtained by impedance spectroscopy, reducibility samples, H2-TPR, observed. The Ba0.8Mn0.7Cu0.3O3 composition (B0.8MC) showed best catalytic performance (comparable to that 1% Pt/Al2O3 reference sample) during tests conducted under...

We report an atmospheric-pressure deposition method for preparing well-adhered and compact CuInS2 films. The precursor film is obtained by a solution-coating technique subjected to low-cost safe one-step reduction−sulfurization treatment. A maximum thickness of 300 nm achieved per layer, up three layers were sulfurized at time. films characterized X-ray diffraction (XRD), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) visible−near-infrared (vis−NIR) spectrophotometry.
The polymorphism of BaTi1−xFexO3−δ solid solutions: 0 < x 0.1, prepared by a sol–gel method, has been determined and presented in the form temperature–composition phase diagram for T > ∼1000 °C.
