The Impact of Ammonium Fluoride on Structural, Absorbance Edge, and the Dielectric Properties of Polyvinyl Alcohol Films: Towards a Novel Analysis of the Optical Refractive Index, and CUT-OFF Laser Filters

The new proton-conducting composite electrolyte films (PCCEFs) consisting of polyvinyl alcohol (PVA) with varying ammonium fluoride salt concentrations were created using an expanded liquid casting process. X-ray diffraction (XRD) study confirms the (CEFs) formation. improvement in AMF02 doping compared to PVA matrix film approach resulted decreased variation crystalline size values, thus explaining how [NH4+] and polymer interact. band gaps decrease when filler concentration increases due increased crystallite size. suggested composites evaluated successful CUT-OFF laser filters attenuation, as well limiting power systems. For 11.11 wt% salt, highest DC conductivity was 73.205 × 10−9 (siemens/m) at ambient temperature. Our dielectric results demonstrate that CEFs are usually suitable for optoelectronic There is a huge need develop low permittivity microelectronic devices high-frequency region.
