| 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 | |
