“…The Raman spectrum plotted for RGO is characterized by two bands centered at 1581 cm −1 (the maximum assigned to a G band that confirms the graphitic nature of the filler) and at 1345 cm −1 (the D band that can be associated with the sp 2 carbon out-of-plane vibration from graphene). In the spectra of the Y 2 O 3 -RGO composite, the existence of similar peaks can be observed, but with a slight shift, broadening of the bands and an increase in the intensity of the peaks as a result of the insertion of the oxide between the graphene sheets [5,8,10]. The SEM image in Figure 3a for the Y 2 O 3 sample highlights the formation of agglomerated particles (without defects on the surface), for which an average particle size of 30-40 nm was found.…”

“…In the spectra of the composites, the existence of the characteristic peak of Y-O bonds can be observed, but with a very slight shift of it towards lower wavenumbers (560 cm −1 ) compared to the oxide nanoparticles and the disappearance of the OH band, as a result of the interference with the carbon material. In IR spectroscopy, the RGO does not show any specific absorption band, which is the reason why the presence of RGO in composites was studied using Raman spectroscopy [5,[8][9][10][11]. Figure 2 shows the Raman spectra for the RGO and the Y2O3-RGO nanocomposite.…”

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.

Metal-free graphitic carbon nitride (gC3N4) is proving as a growing star of the carbon nitride family due to its glamorous electrical, optical, and thermal properties. Blending of zirconium oxide (ZrO2) semiconductor with different weight percentage improves the properties of the pure gC3N4. In this work, we used the ultrasonic sound wave method to synthesize gC3N4/ZrO2 nanocomposite. Characterization techniques such as X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HR-TEM), Fourier transforms infrared microscopy (FTIR), UV-visible, and photoluminescence were used to characterize the as-synthesized gC3N4, ZrO2, and gC3N4/ZrO2 nanocomposite. The XRD measurement method confirmed the crystalline nature and determined the average particle size of the composite. Fourier transform infrared (FTIR) spectroscopy was performed to examine the presence of functional groups in synthesized materials. Bandgap energy of 2.98 eV and light absorbed in the range of 250 nm - 450 nm was recorded by UV visible spectroscopy. Photoluminescence spectroscopy revealed photon emission in the range 450 nm -530 nm of the synthesized materials. Dielectric constant, refractive index (n=1.5), and electrical conductivity (2.63 × 10-3 S/cm) were computed using LCR meter and I-V graph. Lower dielectric constant, refractive index, optimized optical band gap energy, and higher electron-hole recombination rate of gC3N4/ZrO2illustrated a successful emissive layer for organic light-emitting diode applications.
