Abstract

The ternary Cu-Bi-S based semiconductor with abundant and environmental-friendly elements may provide alternative choice for near-infrared (NIR) light-emitting sources. High-quality copper bismuth sulfide Cu ₄Bi₄S₉ (CBS) nanobelts of controllable lengths up to 1 cm were synthesized through a modified solvothermal route by using solvents of varied boiling points (BP) and changing reaction temperatures (RT) to control the competition of efficient collision of Cu₄Bi ₄S₉ seeds, intermediate species and precursors and growth of Cu₄Bi₄S₉ nanobelts. Their NIR photoluminescence (PL) of Cu₄Bi₄S₉ nanobelts was firstly observed in the range of 1400-2200 nm, which showed the transition characteristics of mixed direct and indirect-bands nearby. The absorption and PL spectral data could be well accounted for by the ab initio band calculations of Cu₄Bi₄S₉.
