Multifunctional cellulose-paper for light harvesting and smart sensing applications
António Vicente,Andreia Araújo,Manuel J. Mendes,Daniela Nunes,Maria João Oliveira,Olalla Sanchez-Sobrado,Marta Ferreira,Hugo Águas,Elvira Fortunato,Rodrigo Martins +9 more
TL;DR: In this paper, the state-of-the-art related to the integration and optimization of photonic structures and light harvesting technologies on paper-based platforms, for applications such as Surface Enhanced Raman Scattering (SERS), supporting remarkable 107 signal enhancement, and photovoltaic solar cells reaching ∼5% efficiency, for power supply in standalone applications.
Journal ArticleDOI
High quality conductive gallium-doped zinc oxide films deposited at room temperature
Elvira Fortunato,V. Assunção,Alexandra Gonçalves,A. Marques,Hugo Águas,Luís Pereira,Isabel M.P.L.V.O. Ferreira,Paula M. Vilarinho,Rodrigo Martins +8 more
TL;DR: In this paper, transparent and highly conducting gallium-doped zinc oxide films were successfully deposited by rf sputtering at room temperature, achieving a transmittance in the visible spectra between 80 and 90% and a refractive index of approximately 2, which is very close to the value reported for bulk material.
