“…The optical properties of polymer electrolytes have been studied intensively because of their wide applications in electronic and optical devices, such as chromic display and optoelectronic devices [ 25 ]. Recently, many laboratories have been supported by various companies in which large efforts are devoted to developing new materials to be used in photonic and optoelectronic devices, such as light-emitting diodes (LEDs), organic photovoltaic devices and polymer lasers [ 71 ]. From the literature, it is noted that UV–vis spectroscopy has been commonly used for optical and electronic characterizations of polymer electrolytes [ 25 , 72 , 73 , 74 , 75 ].…”

Polymer electrolytes and composites have prevailed in the high performance and mobile marketplace during recent years. Polymer-based solid electrolytes possess the benefits of low flammability, excellent flexibility, good thermal stability, as well as higher safety. Several researchers have paid attention to the optical properties of polymer electrolytes and their composites. In the present review paper, first, the characteristics, fundamentals, advantages and principles of various types of polymer electrolytes were discussed. Afterward, the characteristics and performance of various polymer hosts on the basis of specific essential and newly published works were described. New developments in various approaches to investigate the optical properties of polymer electrolytes were emphasized. The last part of the review devoted to the optical band gap study using two methods: Tauc’s model and optical dielectric loss parameter. Based on recently published literature sufficient quantum mechanical backgrounds were provided to support the applicability of the optical dielectric loss parameter for the band gap study. In this review paper, it was demonstrated that both Tauc’s model and optical dielectric loss should be studied to specify the type of electron transition and estimate the optical band gap accurately. Other parameters such as absorption coefficient, refractive index and optical dielectric constant were also explored.

“…Characterizations of polymers’ optical properties, such as optical absorption, infrared dichroism, luminescence spectra, and Raman polarization, are among the vital methods to study electronic characteristics [ 18 , 19 , 20 ]. Lately, numerous laboratories are supported by many companies, and their works are devoted to creating new materials to be utilized in optoelectronic and photonic devices, for example, organic photovoltaic, LEDS, and polymer lasers [ 21 ]. In earlier studies, the optical characteristics of polymers incorporated with Pb(ZrTi)O 3 and PbTiO 3 NPs have been studied.…”

In the current study, the film fabrication of polystyrene (PS) based polymer nanocomposites (NCs) with tuned refractive index and absorption edge was carried out using the solution cast method. X-ray diffraction (XRD) and ultraviolet-visible (UV-Vis) light characterization techniques were performed. The structural and optical properties of the prepared films were specified. The hump of PS decreased significantly when SnTiO3 nanoparticles (NPs) were introduced. Sharp and high intense peaks of SnTiO3 NPs at a high filler ratio were observed. The crystalline size was determined for SnTiO3 NPs from the sharp crystalline peaks using Debye-Scherrer’s equation and was found to be 25.179 nm, which is close enough to that described by the supplier. Several optical parameters, such as absorption coefficient (α), refractive index (n), and optical dielectric properties, were investigated. The absorption spectra were tuned with increasing SnTiO3NPs. Upon the addition of the NPs to the PS host polymer, the absorption edge undergoes shifting to lesser photon energy sides. The optical dielectric constant (ε′) was correlated to the refractive index. The study of the optical band gap was conducted in detail using both Tauc’s model and the optical dielectric loss (ε″) parameter. The results showed that the ε″ parameter is noteworthy to be measured in the optical band gap study of materials.
