Resumen
Silver besides being a good electrical conductor has important optical properties. The very high optical reflectance of
silver in the visible and near infrared ranges makes it one of the most employed materials in applications which go since
mirrors of home-use until thin films for applications in the solar control area. Encouraged by this fact in this work we
report a study which goal was to investigate the photonic properties of a periodic structure of silver dots deposited on a
glass substrate. The silver dots array was deposited using a materials printer with an ink cartridge containing suspensions
of silver nanoparticles. By using this method it was possible to obtain a typical silver dot with a diameter of the order of
30 μm and an average thickness of 400 nm. The photonic structure considered was a two-dimensional square array of
silver islands with a periodicity parameter of 45 μm covering an area of (1.2 x1.2) mm2. On the other hand also was
deposited a silver continuous thin film using the same method employed to deposit the silver dots array in order to
evaluate and compare the optical properties of both systems.
The optical properties of both, the photonic structure and the continuous thin film, were evaluated measuring the optical
transmittance as a function of wavelength from 350 to 2400 nm using a spectrophotometer.
The results show an enhancement of the magnitude of the optical transmittance in the UV-VIS range of the photonic
structure regarding to the continuous thin film. The array of silver islands with characteristic dimensions of some tens of
micrometers has photonic properties that allow it to increase and modify its optical transmittance, essentially only in the
optical range from 350-800 nm in a similar way as occurs in a photonic crystal in the sub-micrometric scale
