Synthesis and optical properties of tetrapod-like ZnSSe alloy nanostructures
Tetrapod-like ZnS1-xSex alloy nanostructures (T-ZnS1-xSex) of different compositions (0 <= x <= 1) are synthesized by chemical vapor deposition. Their composition-dependent Raman scattering and cathodoluminescence are studied. The single-crystal T-ZnS1-xSex nanostructures exhibit strong and narrow near-band-edge emissions that can be continuously tuned from 330-459 nm (see figure).
