Perovskite Thin Film Synthesised from Sputtered Lead Sulphide
TL;DR: A new method is proposed to produce CH3NH3PbI3, based on a radio-frequency (rf) -sputtering technique that results in a high reproducibility of the films and is compatible with roll-to-roll processes.
Localization of light induced in ordered colloidal suspensions: powerful sensing tools.
Viktor A. Ermakov,Viktor A. Ermakov,Weliton S. Martins,Niklaus Ursus Wetter,Francisco C. Marques,Ernesto Jimenez-Villar,Ernesto Jimenez-Villar +6 more
TL;DR: In this article, the authors studied the light-matter coupling by Raman scattering in colloidal suspensions composed by core-shell TiO2@Silica nanoparticles suspended in ethanol and water solutions and demonstrated that correlation-induced localization with klT much higher than unity and in an ordered colloidal-photonic structure.

TL;DR: This work studies self-organized superlattices of quantum dots of PbS prepared by dropping a monodispersed colloidal solution on a glass substrate at different temperatures and shows that the intensity of the low-angle XRD peaks depends strongly on the drying time (substrate temperature).

Silver nanoparticles produced by laser ablation for a study on the effect of SERS with low laser power on N719 dye and Rhodamine-B
Nelson Fabian Villegas Borrero,José Maria Clemente da Silva Filho,Viktor A. Ermakov,Francisco C. Marques +3 more
TL;DR: In this article, the effect of surface-enhanced Raman spectroscopy (SERS) was investigated in N719 dye thin films deposited on silicon wafer with a thin film of silver nanoparticles (Ag-NPs) fabricated by laser ablation in an aqueous solution, using a NdYAG laser.
