Abstract

SnxGe1−xS, SnxGe1−xSe, GeSxSe1−x, and SnSxSe1−x alloy nanocrystals were synthesized by novel gas-phase laser photolysis. Their composition-dependent lattice parameters and band gap were thoroughly characterized. The SnxGe1−xS and SnSxSe1−x nanocrystals exhibit higher photoconversion efficiency as compared with the end members.
