| Abstract
| - Large-scale synthesis of single-crystal CdS microbelts was achieved by a modified thermal evaporation method,in which an adiabatic layer was used to provide abrupt temperature decrease and high gas concentration forthe microbelt growth. The synthesized CdS microbelts were usually several micrometers in width, 70 nm inthickness, and tens to several hundred micrometers in length. Studies found that the adiabatic layer has greatinfluence on the formation of CdS microbelts. Room-temperature photoluminescence indicated the disappearance of the emission at 1.77 eV, the appearance of an emission at 2.07 eV, and also the enhancement ofthe emission band at 2.38 eV, whose position shifted toward the blue region compared with conventionalnarrow CdS nanobelts. A possible growth mechanism of the CdS microbelts was briefly discussed.
