| چکیده | ||
| This study explores the enhancement of light-emitting diode (LED) performance through the integration of quantum dots (QDs) and plasmonic layers. Simulations were conducted using Lumerical software to analyze the effects of QD size (2, 5, and 10 nm) and plasmonic layer thickness on emitted light intensity and wavelength variations. The results demonstrate that the plasmonic layer significantly enhances the electromagnetic field near the QDs, leading to increased emission light intensity. Changing the QD size influences both the emission wavelength and intensity: smaller QDs shift the emission toward shorter wavelengths and exhibit higher intensity, while larger QDs shift it toward longer wavelengths with lower intensity. This combined approach offers an effective strategy for optimizing LED efficiency, enabling precise wavelength control and improved energy performance. The findings contribute to advancements in LED technology, high-quality displays, and energy-efficient nanoscale light sources, and also suggest promising directions for future research. | ||
