Coexistence of two-photon absorption and saturable absorption in ion-implanted platinum nanoparticles in silica plates
(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 ...
Superlinear photoluminescence by ultrafast laser pulses in dielectric matrices with metal nanoclusters
(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 ...
