Near-IR Emission and upconversion luminescent properties of Tb3+/Yb3+ Co-doped HfO2/SiO2 nanoparticles
Autor: Lucas A. Rocha, Anastasiya Sedova, S. Carmona-Téllez, Ciro Falcony, Jesús Uriel Balderas, Vicente Vargas, Iván Merlin
Publikováno v: Ceramics International. 48:6007-6015
The luminescent characteristics of spherical hafnia/silica (HfO2/SiO2) nanoparticles (NPʼs) co-doped with Tb3+/Yb3+ were analysed. These NPʼs were synthesized using the spray pyrolysis technique. The addition of SiO2 and Tb3+/Yb3+ was found to indu

Luminescent characteristics of Eu2+/Li+ doped (La-Al)2O3 phosphors and PMMA films activated with them
Autor: L. Mariscal-Becerra, C. Falcony, S. Carmona-Téllez, R. Vázquez-Arreguín, J. U. Balderas-Aguilar, G. Alarcón-Flores, H. Murrieta
Publikováno v: Revista Mexicana de Física. 64:447-455
The effect of Li co-doping on the blue luminescence of Eu2+ doped (La-Al)2O3 phosphors and its incorporation into poly (methyl methacrylate) PMMA films are reported. The phosphors were synthesized by a simple two-step process in which the (La-Al)2O3

Visible and near infrared upconversion photoluminescence from Y2O3:Er3+, Yb3+, Li+ phosphors under 1532 nm excitation light
Autor: S. Carmona-Téllez, J.G. Cabañas-Moreno, C. Falcony, E.F. Huerta
Publikováno v: Journal of Alloys and Compounds. 732:422-428
Visible and near-infrared upconversion luminescence from Y2O3 co-doped with Er3+, Yb3+ and Li+ phosphors under continuous excitation with 1532 nm light are reported. The upconversion emissions at 530–570 nm (green light emission region), and 640–
