Synthesis and Optical Properties of Tetrapod‐Like ZnSSe Alloy Nanostructures

Abstract

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).
