We report the first observation of room-temperature quantum-confined photoluminescence (PL) from low-dimensional Ge(1-x)Sn(x)/Ge superlattices (SLs) up to a high Sn content of 6.96%. Both direct and indirect emissions associated with the interband transitions between minibands in the conduction bands and valence band were observed at room temperature. As(More)
