    Nanoscale semiconductor materials have large tolerance to lattice mismatches, which enables an almost arbitrary control of alloy composition and bandgap energy. In this Review, semiconductor alloy nanomaterials are examined, and their synthesis, properties and potential for applications — such as lasers, solid-state lighting and solar cells — are discussed.
