Sumario: | Low-dimensional semiconductors exhibit remarkable performances in many device applications because of their unique physical, electrical, and optical properties. In this paper, we report a novel and facile method to synthesize In(2)S(3) quantum dots (QDs) at atmospheric pressure and room temperature conditions. This involves the reaction of sodium sulfide with indium chloride and using sodium dodecyl sulfate (SDS) as a surfactant to produce In(2)S(3) QDs with excellent crystal quality. The properties of the as-prepared In(2)S(3) QDs were investigated and photodetectors based on the QDs were also fabricated to study the use of the material in optoelectronic applications. The results show that the detectivity of the device stabilizes at ~ 10(13) Jones at room temperature under 365 nm ultraviolet light irradiation at reverse bias voltage. |
