Hole transport layer-free deep-blue OLED with outstanding colour purity and high efficiency

Abstract

Hole transport layer-free deep-blue OLED was fabricated and excimer emission was intensively suppressed by modifying ITO. It displayed CIE color coordinates of (0.162, 0.028), the deepest blue among the blue OLEDs ever reported. Meanwhile, FWHM of only 38 nm, maximum EQE of 4.43% and slight efficiency roll-off were obtained.
