The present invention relates to an article having a surface coated with a nanostructured temporary super-hydrophobic film having a static contact angle with water of at least 140°, preferably exhibiting multiple length scales of roughness and comprising nanoparticles functionalized with a hydrophobic agent, wherein the functionalization of the nanoparticles with the hydrophobic agent has been performed before said nanostructured temporary super-hydrophobic film is coated on said surface. The surface of the article exhibits a static contact angle with water of at least 60° before being coated with the nanostructured temporary super-hydrophobic film. The treatment according to the invention can be used to provide an antirain function to optical articles having a hydrophobic surface.

An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nanostructured interface. The nanostructured bilayer acts locally on amplitude, phase, or polarization of light, or a combination thereof and imparts a light phase shift that varies as a function of position of the nano structured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film.

The present inventive concept relates to a hybrid wavelength converter including both a metal halide perovskite nanocrystal particles and non-perovskite-based quantum dots or non-perovskite-based phosphors converting a wavelength of light generated from an excitation light source to specific wavelengths, and a light-emitting device including the same. By including metal halide perovskite nanocrystal particles and non-perovskite quantum dots or non-perovskite phosphors in the dispersion medium, the hybrid wavelength converter according to the present inventive concept enables to make simultaneous wavelength conversion to red and green light, and to be optically stable and improved color purity and luminescence performance without changing the emission wavelength range even with a lower cadmium content than the conventional quantum dot wavelength converter.
