“…Most existing flexible displays employ organic light-emitting diodes (OLEDs). Foldable smartphones with OLED displays [1][2][3] are becoming widely available and the first rollable televisions [4] have appeared on the market. Flexible displays widen the applications of electronic displays and greatly reduce manufacturing costs, as they allow for roll-to-roll fabrication [5].…”

Fabrication of high-performance, flexible quantum-dot light-emitting diodes (QLEDs) requires the reliable manufacture of a flexible transparent electrode to replace the conventional brittle indium tin oxide (ITO) transparent electrode, along with flexible substrate planarization. We deposited a transparent oxide/metal/oxide (OMO) electrode on a polymer planarization layer and co-optimized both layers. The visible transmittance of the OMO electrode on a polyethylene terephthalate substrate increased markedly. Good electron supply and injection into an electron-transporting layer were achieved using WOX/Ag/ WOX and MoOx/Ag/MoOX OMO electrodes. High-performance flexible QLEDs were fabricated from these electrodes; a QLED with a MoOX/Ag/ MoOX cathode and an SU-8 planarization layer had a current efficiency of 30.3 cd/A and luminance more than 7 × 104 cd/m2. The current efficiency was significantly higher than that of a rigid QLED with an ITO cathode and was higher than current efficiency values obtained from previously reported QLEDs that utilized the same quantum-dot and electron-transporting layer materials as our study.

“…In general, Mq 3 molecules have the ability to interact with a wide range of materials comprising metals, metal oxide nanoparticles (NPs), and carbonaceous materials, carbon nanotubes (CNTs), graphene, and graphene oxide (GO). Therefore, integration of the Alq 3 framework with different nanomaterials will produce new composites with promising characteristics that combine inorganic–organic ligands. , In this context, Sharma et al have studied the influence of the DCJTB organic dye on the electronic and spectroscopic features of Alq 3 for modifying OLEDs’ behavior . Furthermore, rare earth metal oxide semiconductors (REMOSs) such as cerium oxide (CeO 2 ), lanthanum(III) oxide (la 2 O 3 ), lutetium(III) oxide (Lu 2 O 3 ), and yttrium(III) oxide (Y 2 O 3 ) have displayed great importance in numerous technological applications thanks to their photostability, redox capabilities, and electromagnetic aspects .…”

In the present study, tris-(8-hydroxyquinoline) aluminum (Alq 3 ) and tris-(8hydroxyquinoline) aluminum/yttrium oxide Alq 3 /Y 2 O 3 were synthesized by a facile chemical route. The crystal structure, surface morphological nature, and particle size were identified by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) micrographs. Ag/Alq 3 /p-Si/Al and Ag/Alq 3 :Y 2 O 3 /p-Si/Al diodes were fabricated by the thermal evaporation technique and the electrical characteristics were evaluated from the I−V plots in dark and under illumination intensity. Thermionic emission theory, Cheung−Cheung, and Nord model have been applied to define the main electronic parameters like series resistance (R s ), barrier height (ϕ b ), and ideality factor (n). The hybrid Ag/Alq 3 :Y 2 O 3 /p-Si/Al diode revealed a nonideal behavior with high shunt resistance R sh and good photocurrent sensitivity. The C/G−V analysis indicated that both C and G are strongly affected by the presence of trapped charge carriers at the interface states. The obtained results indicated that R s was decreased whereas the carrier concentration (N a ) was increased by loading Y 2 O 3 nanosheets.

In this article an attempt has been made to design the meshing structure of Alq3/Alq3:NTCDA/NPB layers based OLED and to determine the the optical characteristics such as PL (photo luminescence), emission rate, and normal spectral density. The studies of all these parameters suggest that the heterostructure system based OLED is useful for the emission of high intense radiations in the visible region (wavelength region ~500 nm).
