Low-color-temperature candlelight organic light-emitting diodes (OLEDs) offer a healthier lighting alternative by minimizing blue light exposure, which is known to disrupt circadian rhythms, suppress melatonin, and potentially harm the retina with prolonged use. In this study, we explore integration of transition metal dichalcogenides (TMDs), specifically molybdenum disulfide (MoS2) tungsten (WS2), into hole injection layers (HILs) OLEDs enhance their performance. The TMDs, are for superior carrier mobility, optical properties, 2D layered structure, were doped at levels 0%, 5%, 10%, 15% in PEDOT:PSS-based HILs. Our findings reveal that 10% MoS2 exhibit notable enhancements power efficacy (PE), current (CE), external quantum efficiency (EQE) approximately 39%, 21%, 40%, respectively. comparison, incorporating WS2 achieve PE 28%, CE 20%, an EQE 35%. enhanced performance MoS2-doped devices attributed balanced transport resulting more efficient operation. These results highlight potential especially MoS2, OLED technology as promising strategy energy efficiency. This approach aligns environmental, social, governance (ESG) goals emphasizing reduced environmental impact promoting ethical practices development. improved metrics these TMD-doped suggest viable path towards creating energy-efficient health-conscious solutions.

Abstract Formamidinium lead bromide (FAPbBr 3 ) perovskite nanocrystals (NCs) are promising for display and lighting due to their ultra-pure green emission. However, the thermal quenching will exacerbate performance degradation in practical applications, which is a common issue halide perovskites. Here, we reported heat-resistant FAPbBr NCs prepared by ligand-engineered room-temperature synthesis strategy. An aromatic amine, specifically β-phenylethylamine (PEA) or 3-fluorophenylethylamine (3-F-PEA), was incoporated as short-chain ligand expedite crystallization rate control size distribution of NCs. Employing this engineering approach, synthesized high quality with uniform grain reduced long-chain alkyl ligands, resulting substantially suppressed enhanced carrier transportation films. Most notably, more than 90% room temperature PL intensity 3-F-PEA modified film preserved at 380 K. Consequently, fabricated EL devices external quantum efficiency (EQE) 21.9% luminance above 1,000 cd m −2 , demonstrated less 10% loss EQE 343 This study introduces novel method synthesize efficient exceptional stability, paving way advanced optoelectronic device applications.
