Charge storage layers are an important component of electrochromic devices, which expected to exhibit high capacity and transparency as well fast electron transfer rates. However, these often rely on the (de)intercalation ions into crystal lattice material therefore require optimization be compatible with non-intercalating electrolytes. In this report, post-modification mesoporous antimony-dope...

Understanding cell-biomaterial interactions is critical for the control of cell fate for tissue engineering and regenerative medicine. Here, cerium oxide nanoparticles (CeONPs) are applied at different Ce4+/Ce3+ ratios (i.e., 0.46, 1.23, and 3.23) to titanium substrate surfaces by magnetron sputtering and vacuum annealing. Evaluation of the cytotoxicity of the modified surface to cultured rat b...

Boron- and cerium-doped titania (Anatase) were prepared via sol-gel method. Phase composition morphology assessed by X-ray diffraction (XRD), scanning electronic microscopy (SEM), BET, diffuse reflectance spectra (DRS), XPS. Photo-electrochemistry of these materials, deposited onto fluorine-doped SnO2 (FTO), was investigated in acid acid-containing methanol. The boron-doped sample showed the be...

Blue-light-excitable red-emitting phosphors with high thermal stability are essential for fabricating white light-emitting diodes (WLEDs). Herein, Ce3+-doped SrLaScO4 (SLO:Ce3+) phosphor is discovered to have an abnormal red emission band centered at 640 nm when excited 440 nm. Spectroscopy and structural analyses confirm that Ce3+ ions occupy the [LaO8] polyhedrons competitively, generating a ...

Afterglow properties of persistent phosphors are attracting a great deal attention in the fields bioimaging, sensing, labeling, safety, or security. Complex garnet oxides, especially those doped with Ce3+ and Cr3+, particularly relevant to this end since their luminescence can be tuned through matrix composition activated by visible light, contrast vast majority that require UV excitation. Most...

Ce3+-activated Gd3Al5O12 garnet, effectively stabilized by Lu3+ doping, has been developed for new yellow-emitting phosphors. The powder processing of [(Gd1-x Lu x ) 1-y Ce y ]3Al5O12 solid solutions was achieved through precursor synthesis via carbonate precipitation, followed by annealing. The resultant (Gd,Lu)AG:Ce3+ phosphor particles exhibit typical yellow emission at ∼570 nm (5d-4f transi...

In this study PbZrO3 was prepared as a matrix by the sol-gel process and is characterized by XRD and SEM techniques. The particle size of the synthesized nanocomposite is evaluated about 43 nm. The Lead Zirconate is then doped with Ce3+/TiO2 in different ratios. Nanocomposites are added in the reaction in a photoreactor with a pollutant (an Azo dye) and as a result the degradation percentage is...
