a Optical images revealing LiCl-based solution (top) and nanocomposite (bottom) inks extruded from a syringe. b Storage moduli (G’) and loss moduli (G”) as a function of shear stress. c Device luminance and ionic conductivity of different inks. The devices are powered by square wave voltages (20 kHz, 80 V). d Luminous patterns generated by painting with aqueous solutions (left) and by stamping (middle) and stencil printing (right) with nanocomposite inks. Scale bars: 1 cm.
