“…Figures 4 and 5 show that the energy gap for allowed and forbidden for the PVA/PEG/TiN nanocomposite respectively. It is obtained that the Eg reduces when the rise of content of TiN NPs attributed to formation of defects and levels inside band gap therefore the value of Eg will be reduced [27][28][29][30][31][32][33][34][35][36][37].…”

In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This nanocomposite was analyzed to use a Spectrophotometry with a spectral region of 200-800 nm. The absorption enhances when the added TiN NPs to the polymeric matrix which may be used for various applications such as optoelectronic detector. The optical energy gap for indirect transition (allowed and forbidden) decreased as TiN NPs content increases. Moreover, all optical constants have been determined.

“…(4,5) demonstrate that the gap of energy for "allowed and forbidden" for the PEG/Fe2O3nanocompositeindividually. It is obtained that the Eg reduce when the increase of contented of Fe2O3 NPs which due to creation of stageswithin band gap hence the value of Eg will be reduce [23,24]. The "coefficient extinction" (k) and "index of refractive" (n) of PEG/Fe2O3nanocomposites are represent in figs.…”

In this study, casting technique were used to fabricate of PEG/Fe2O3 nanostructures with variant content of Fe2O3 NPs to employ in different optical fields. The results showed that the absorbance of PEG increases as the concentrations of Fe2O3 nanoparticles increase while the transmittance and energy gap of PEG decrease with increase concentrations of Fe2O3 NPs. The optical factors of PEG/Fe2O3 nanocomposites are enhanced with adding of the Fe2O3 NPs content. The optical characteristics results of the PEG/Fe2O3 nanocomposites proved that may be employed in optoelectronic detector.

“…Examples of blue TADF materials are given in Table 3. Calculation of light output efficiency from the OLED OLEDs are eco-friendly and consume less power than other lighting devices (incandescent lamp, discharge tube, fluorescence bulb) [60][61][62]. In a single organic layer OLED, holes and electrons are ejected from anode and cathode, respectively, and are generated at the opposite pole of the device with the applied voltage.…”

“…The strong force makes the opposite charges rush toward each other and combine as an exciton at the organic layer. After a lifetime, the excitons disappeared by emitting a light [62,63]. The OLED emits light of good quality and better external quantum efficiency (EQE).…”

In the present time, organic light-emitting diode (OLED) is a very promising participant over light-emitting diodes (LEDs), liquid crystal display (LCD), and also another solid-state lighting device due to its low cost, ease of fabrication, brightness, speed, wide viewing angle, low power consumption, and high contrast ratio. The most prominent layer of OLED is the emissive layer because the device emission color, contrast ratio, and external efficiency depend of this layer's materials. This review ruminates on the basics of OLEDs, different light emission mechanisms, OLEDs achievements, and different types of challenges revealed in the field of OLEDs. This review's primary intention is to broadly discuss the synthesizing methods, physicochemical properties of conducting polymer polymethyl methacrylate (PMMA), and its polymeric nanocompositebased emissive layer materials for OLEDs application. It also discusses the most extensively used OLED fabrication techniques. PMMA-based polymeric nanocomposites revealed good transparency properties, good thermal stability, and high electrical conductivity, making suitable materials as an emissive layer for OLED applications.
