Demonstration of organic light emitting diodes fabricated on flexible Al2O3-embedded poly(dimenthylsiloxane) substrates

[[abstract]]This study presents a flexible substrate using poly(dimenthylsiloxane) (PDMS) to fabricate organic light-emitting diodes (OLEDs). To reduce surface roughness and enhance surface stiffness necessary for OLED fabrication, we optimized the constituents of PDMS precursor and introduced a strength-enhancement layer, which comprises Al2O3 nanoparticles, and embedded it near the surface. Experimental results showed the tris(8-hydroxyquinolinato) aluminum (Alq3)-based OLEDs fabricated on the substrate can be successfully turned on at a low threshold voltage of 2.2 V with a bending radius of 3.0 cm. © 2009 The Japan Society of Applied Physics.[[fileno]]2030180010012[[department]]電機工程學
