N2 - We report on the fabrication of metal-oxide/metal-oxide/metal thin films multi-stacked configuration used as a photonic cooler based on a near infrared light filter, with anti-dust and antireflective properties. The optimized structure considers TiOx as a top layer, NiO as the buffer layer, and Ag as the reflective hot-mirror layer of the near infrared (NIR) light spectrum. This configuration was developed by a thermal e-beam deposition process without breaking the vacuum, where all the oxides layers were grown reactively under oxygen atmosphere. TiOx layer has been found super-hydrophilic, thereby providing a self-cleaning adn anti-dust properties to the photonic cooler. Filtration (i.e. cutoff) of the IR spectrum has been improved with the stacking configuration of inorganic metal oxide (Low refractive index, TiOx)/metal oxide (High refractive index, NiO, MoOx)/ metal layer (Ag, Al). Among all the configurations, MoOx/TiOx and NiOx/TiOx layers have shown higher transmittance (T%) in the visible range compared with the single TiOx layer. Moreover, adding a metal layer of (Ag or Al) resulted in wavelength cut-off starting from 800 nm by reflecting (>70%) of light. Our results confirm the commercial potential of this multi-stack structure due to its multi-functionalities, such as IR filtering, anti-reflection coating in the visible range, and anti-soiling capability, in addition to its scalability.
