The optimized values of optical transmittance and sheet resistance of AgNWs covered graphene were 87.7% at 375 nm and 50 +/- 5 Omega/sq, respectively. Upon applying the AgNWs on graphene electrode, the UV-LED exhibited uniform bright light emission with a reduction in the forward voltage and about four-fold increase in the electroluminescence intensity. We attribute the observed performance improvements to a reduction in the sheet and contact resistances.
