Strong green luminescence (around 2.37 eV) was observed in two InAlGaN thin film samples, which were originally prepared for applications in the ultraviolet range. Fourth harmonic (266 nm) of a Q-switch Nd:yttritium-aluminum-garnet laser was used as the excitation source. Observation of green luminescence was attributed to the formation of indium-rich clusters, which formed localized states in the quaternary films.
