Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates
Torres Torres, Carlos; Bornacelli, J.; Can-Uc, Bonifacio Alejandro; Silva Pereyra, Héctor Gabriel; Rodríguez Fernández, Luis; Ávalos Borja, Miguel; Labrada Delgado, Gladis Judith; Cheang Wong, Juan Carlos; Rangel Rojo, Raúl; Oliver y Gutiérrez, Alicia María (Optical Society of America, 2018)"Platinum nanoparticles were nucleated in a high-purity silica matrix by an ion-implantation method. The third-order nonlinear optical response of the samples was studied using femtosecond pulses at 800 nm with the z-scan ... -
Platinum nanoclusters in silica: Photoluminescent properties and their application for enhancing the emission of silicon nanocrystals in an integrated configuration
Bornacelli, J.; Silva Pereyra, Héctor Gabriel; Rodríguez Fernández, Luis; Ávalos Borja, Miguel; Oliver G., Alicia (2016-09)"We studied photoluminescence of ion implanted platinum nanoclusters embedded in silica. Pt ions were implanted at 2 MeV and the Pt nanoclusters were then nucleated by thermal treatment under either argon, air, or a reducing ... -
Superlinear photoluminescence by ultrafast laser pulses in dielectric matrices with metal nanoclusters
Bornacelli, J.; Torres Torres, Carlos; Silva Pereyra, Héctor Gabriel; Labrada Delgado, Gladis Judith; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver y Gutiérrez, Alicia María (Nature Publishing Group, 2019)"An intense photoluminescence emission was observed from noble metal nanoclusters (Pt, Ag or Au) embedded in sapphire plates, nucleated by MeV ion-implantation and assisted by an annealing process. In particular, the ...
