ZnS microbelts with flat morphology have been synthesized through a physical vapor transportation method inside an induction furnace. The structure, morphology and cathodoluminescence properties of ZnS microbelts have been studied using various characterization methods. The width of the ZnS microbelts can be up to several micrometers and the length can reach to tens of µm. Optical measurements indicate that the ZnS microbelts show a sharp UV emission at 337 nm, a weak band at 377 nm, a strong visible luminescence band at 464 nm, and a shoulder at 665 nm. Finally, possible explanations for the optical emissions of ZnS microbelts are discussed.
