PERFORMANCE ENHANCEMENT OF WOLEDs USING CdSe/ZnS QUANTUM DOTS AND ITO NANOROD STRUCTURES

Abstract

This study examines the impact of ITO nanorod structures on the efficiency of white organic light-emitting diodes (WOLEDs) with CdSe/ZnS quantum dots (QDs). The integration of nanorods significantly improved charge injection, luminance, and luminous efficiency, while maintaining stable white-light emission. Experimental results showed a reduction in turn-on voltage (from 3.5V to 2.8V), a 2.2-fold increase in luminance (from 7,191 cd/m² to 16,333 cd/m²), and an improvement in luminous efficiency (from 2.30 cd/A to 3.12 cd/A). The CIE chromaticity coordinates remained stable at (0.329, 0.331), ensuring color accuracy. These findings underscore the potential of ITO nanorods for high-performance, energy-efficient OLED displays and lighting applications.
