Strain-induced subwavelength-structure for haze-free and highly transparent flexible plastic substrate

Abstract

This paper presents a method to produce subwavelength-scale (< 250 nm) AgCl nanostructures on flexible plastic film, which is indispensable for a high-efficient flexible display. Using Cl2 plasma treatment on Ag-coated plastic film, AgCl nanostructures were produced through reaction of Ag atoms with Cl radicals. During the reaction, the volume of AgCl expands, leading to drastically changed surface morphology from a two-dimensional (2D) flat Ag surface to 3D subwavelength-scale AgCl nanostructure. The optical properties of the AgCl on the plastic film remarkably enhanced from 89.6 % to 93.4 % in average transmittance ranged between 400 and 800 nm, while the average haze was retained below 0.3 %. Consequently, OLEDs based on the subwavelength-scale AgCl nanostructure enhanced luminance efficiency (88.6 cd A-1 at 1,000 cd m-2) up to 10.7 % without modifying angular emission pattern; superior to those of as-received PI film (efficiency of 80.0 cd A-1). The nanostructure enhances transmission of electromagnetic (EM) wave as well as prohibits scattering of EM wave, confirmed by finite-difference time-domain simulation and rigorous coupled wave analysis.
