Organic light-emitting diodes (OLEDs) have emerged as one of the most promising technologies for next-generation displays and solid-state lighting. However, improving device efficiency, charge balance, color stability, and operational performance remains a major scientific and technological challenge. This seminar presents our recent research on the design and fabrication of high-performance OLEDs through advanced thin-film deposition techniques and interface engineering. Various strategies, including controlled thermal evaporation, graded and periodic deposition profiles, host–guest emissive systems, and metal-complex-based emitting materials, are discussed as effective approaches for optimizing charge transport, exciton recombination, and light emission. The presentation further highlights the influence of deposition parameters on electroluminescence characteristics, Förster energy transfer, molecular interactions, and device architecture. The effects of graphene-based transparent electrodes and patterned electrode structures on optical and electrical performance are also presented. The results demonstrate that precise control over thin-film deposition and interface engineering provides an effective pathway toward highly efficient OLED devices with improved luminance, spectral stability, and overall performance. The seminar concludes with future perspectives on OLED technology and its integration into emerging photonic and optoelectronic applications.
