This study investigates the effects of incorporating gold nanoparticles (Au NPs) into a MEH-PPV polymer on its fluorescent properties. Analysis of the fluorescence spectrum of the polymer reveals a significant increase in fluorescence intensity upon the addition of Au NPs. Further investigation using Laser Induced Fluorescence (LIF) spectra demonstrates that the purified polymer emits light […]
Two dimensional all dielectric grating metamaterial based on polydimethylsiloxane and TiO2 materials were prepared via sputtering method in two different configurations as PDMS/TiO2 (50 nm)) and 2D grating (etalon) TiO2 (50 nm)/PDMS/TiO2 (50 nm). As it was measured by a charged coupled device (CCD) camera, the hotspots confirm four points symmetry of the structure and […]
