摘要：

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 (Alq(3))-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.
