Single-crystalline CdS nanobelts demonstrate excellent field-emission properties for the first time. Individual CdS nanobelts are assembled for high-performance visible-light photodetectors with an ultrafast response time of ∼20 μs and ultrahigh quantum efficiency of 1.9 × 107%. The results suggest a high potential of utilizing these CdS nanobelts as optoelectronic nanodevices.
