This article comprehensively analyzes how phenol red dye affects the optical, structural, and electrical properties of sodium bromide‐doped polymer electrolyte films based on sodium carboxymethyl cellulose. Conventional solution casting technique has been employed to prepare the electrolytes. The optical analysis reveals that incorporating the phenol red dye improves the optical properties. Fourier transform infrared spectroscopy is used to study the kind of complexation between the polymer and dopants. Scanning electron microscope micrographs of the electrolytes indicate the acquisition of free volume on the surface of the polymer matrix. The electrical properties are studied using impedance analyzer, which shows that the ionic conductivity increases when the dye is incorporated. The electrolyte system incorporated with 0.25 wt% of the dye exhibits the highest conductivity among the other systems. Photoluminescence investigation demonstrates that doping increases the intensity of the photoluminescence emission as it minimizes the free volume size. Commission Internationale de l'Eclairage (CIE) chromatograph studies indicate that the doped samples emit a yellow color with a color purity of 97%. All in all, the findings imply that adding dye to the polymer matrix increases the electrical and visual characteristics of the polymer electrolyte.Highlights Phenol red dye improves the optical properties of sodium carboxymethyl cellulose‐based polymer electrolytes. Scanning electron microscope micrographs reveal the creation of free volume on the surface of electrolyte films. Analysis of electrical properties shows a slight increase in ionic conductivity with dye incorporation. Photoluminescence intensity increases with dye due to reduced free volume size. Doped samples emit 97% purity yellow enhancing electrical and optical properties.

“…On the other hand, Poly-methylmethacrylate (PMMA) is a commonly used polymer for the preparation of thin film as most of the material gets decomposed into PMMA [54][55][56]. In addition to this, PMMA has moderate properties such as low-cost, hightransparency window with good flexibility, good physical and chemical properties, and easy handling capabilities, which stem researchers to use it in a wide range of applications [57][58][59].…”

By employing the ultrafast Z-scan technique, we characterize the nonlinear absorption property of PMMA/Bismuth Selenide (Bi2Se3) composite with varying concentrations. We report the fabrication of bismuth selenide (Bi2Se3) nanoplate (topological insulator (TI)) doped poly methyl methacrylate (PMMA) thin film with varying doping concentrations. The effect of Bi2Se3 on structural and linear properties of PMMA thin film has been investigated through UV-Vis spectroscopy, scanning electron microscope (SEM), and Energy dispersive X-ray spectroscopy (EDS) elemental mapping techniques. Furthermore, the nonlinear optical absorption property of PMMA and PMMA/Bi2Se3 composites have been performed employing a single beam open aperture z-scan technique under femtosecond laser excitation at 750 nm. The z-scan results exhibit an enhancement of reverse saturable absorption (RSA) property with an increased nonlinear absorption coefficient (β) of the PMMA/Bi2Se3 composites compared to pure PMMA measured with intensity at 320 GW/cm2. The RSA response gets enhanced with the increase in doping concentration also. Our experimental observations reveal that PMMA/Bi2Se3 composite can provide promising a platform to realize photonic devices such as optical limiters, optical switches, and efficient protectors from high power sources.
