Comparative study of kinetic parameters induced by different excitation sources: using a novel and user-friendly glow curve deconvolution spreadsheet

Autor: V. M. Castaño-Meneses, H. A. Durán-Muñoz, Claudia Sifuentes-Gallardo, R. Sánchez-Zeferino, M. Hernández-Ortiz, J. I. Galvan-Tejeda

Publikováno v: Journal of Materials Science: Materials in Electronics. 29:15732-15740

In this work, we performed a comparison study between the kinetic parameters associated to the KCl:Eu2+ crystal, which is excited separately with ultraviolet light and a source of beta particles. To obtain the kinetic parameters easily (peak and trap

Fabrication, structural properties, and tunable light emission of Sm3+, Tb3+ co-doped SrSnO3 perovskite nanoparticles

Autor: C.G. Pérez-Hernández, R. Sánchez-Zeferino, Mario Enrique Álvarez-Ramos, U. Salazar-Kuri

Publikováno v: Chemical Physics. 551:111324

Sm3+, Tb3+ co-doped SrSnO3 perovskites were successfully prepared by the sonochemical method and solid-state reactions. X-ray diffraction showed well-defined peak characteristics of the SrSnO3 orthorhombic phase, while SEM analysis revealed the forma

Emulation of evolutionary selection as the growth mechanism of supported layered double hydroxide frameworks

Autor: U. Salazar-Kuri, A. Escobedo-Morales, Irving Israel Ruiz-López, M.S. Pedraza-Chan, R. Sánchez-Zeferino

Publikováno v: Applied Clay Science. 210:106159

The evolutionary selection is proposed as the actual growth mechanism of supported layered double hydroxide (LDH) frameworks constituted by interconnected sheet-like structures with apparent preferential orientation. This growth mechanism was emulate

ZnS and ZnO nanocomposite for near white light tuning applications

Autor: R. Sánchez-Zeferino, Mario Enrique Álvarez-Ramos, Arturo A. Ayon, R. Lopez-Delgado, A. Cordova-Rubio, R. C. Carrillo-Torres, J E. Pelayo-Ceja, A. Zazueta-Raynaud

Publikováno v: 2019 Symposium on Design, Test, Integration & Packaging of MEMS and MOEMS (DTIP).

There is currently an increased interest in demonstrating white light emitting devices that exhibit a higher energy efficiency compared to the ubiquitous incandescent sources and that are at the same time cost-competitive as well as compatible with a
