- Silver and gallium form an alloy Ag<sub>2</sub>Ga via a room temperature spontaneous self-assembly that exhibits remarkable mechanical and electrical properties  suitable for nanoscale measurements . However, whether photon excitation of plasmons in this emerging nanomaterial is retained or not has not been established. Here, we present a thin lm formation of Ag<sub>2</sub>Ga via a spreading- reactive process of liquid Ga on an Ag lm and a characterization of its dielectric function (E) = 1(E) - i <sub>2</sub>(E) in the photon energy range 1.42 eV E <4.2 eV. It is observed that while the plasmon damping increases, near an energy of 3.4 eV, the real part of exhibits a crossing with respect to that of Ag. Furthermore, the impact of new plasmon supporting materials  is discussed and in order to enable further applications in plasmonics, the possibility of photon excitation of surface plasmons in Ag<sub>2</sub>Ga is studied.
