Transparent chromatic electrode using the mixture of silver nanowire and silver nanoprism

In this research, we studied a chromatic transparent silver nanowire (Ag NW) electrode using a silver nanoprism (Ag NP). Ag NW and Ag NP were produced using a chemical synthesis method (polyol method) and deposited on substrate via spray method. NW electrode showed a more than 80% transmittance and no or low conductivity without high temperature annealing process. In the case of applying an annealing process, a 13 Ω/□ sheet resistance was measured. ectrode, which consisted of a mixture of Ag NW and Ag NP, showed a reduced transmittance of about 70%. However, by applying Ag NPs to a conventional bare Ag NW electrode, we were able to add a chromatic characteristic to the transparent electrode; this addition was induced by the localized surface plasmon resonance (LSPR) and the low sheet resistance, even though no annealing process was applied.
