Rocha, Leandro S.R.; Amoresi, Rafael A.C. [UNESP]; Moreno, Henrique [UNESP]; Ramirez, Miguel A. [UNESP]; Ponce, Miguel A.; Foschini, Cesar R. [UNESP]Made available in DSpace on 2020-12-12T02:44:40Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-06-30; 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, photoluminescent, magnetic, electric, and gas-sensing properties of these systems are str...

Rocha, Leandro S. R.; Schipani, Federico; Aldao, Celso M.; Cabral, Luis; Simoes, Alexandre Z. [UNESP]; Macchi, Carlos; Marques, Gilmar E.Made available in DSpace on 2020-12-12T02:32:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Lanthanum-doped CeO2 is a promising semiconductor for gas sensing. A combined study applying impedance spectroscopy and first-principles calculations was performed for pure and lanthanum-doped samples. The results showed a strong influence of the localized Ce 4f states on the electrical conduction proce...

Ferreira, Diego H.O.; Vaz, Isabela C.F.; Rubinger, Rero M.; Buono, Camila; Rocha, Leandro S.R.; Ponce, Miguel A.; Longo, ElsonMade available in DSpace on 2020-12-12T02:35:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Low resistive electrodes based on Co and Mo co-doped SnO2 were prepared by the conventional solid-state reaction and sintered at 1250 °C for 2 h. Concentration of Co2O3 precursor was unchanged (1 mol%), while MoO3 was varied (0.25, 0.50 to 0.75 mol%) to promote conductivity. The structural and microstru...
