Single‐crystalline, narrow‐size‐ distribution ultrafine ZnS nanobelts (see figure), revealing a notable quantum‐confinement effect, have been synthesized at a high yield by controlling the evaporation and agglomeration rates. Field‐emission measurements show ultrafine ZnS nanobelts are very good field emitters with a low turn‐on field and high field‐enhancement factor.
