Abstract |
AgInS2 (Silver Indium Sulphide) quantum dots of size ∼ 1.4 nm have been prepared by sonochemical
method using precursor complex. Dodecylamine has been used as capping agent. The Precursor complex,
containing Silver, Indium metal ions and sulphur used for the synthesis of the quantum dots has been prepared
by simple precipitation and filtration. Then the complexes have been irradiated under high intensity
ultrasound to get small size AgInS2 quantum dots within short reaction duration of ∼ 5 minutes. The prepared
quantum dots then have been characterised by XRD, UV-VIS spectroscopy, fluorescence spectroscopy
and DLS analysis. The results show that AgInS2 can be prepared by sonochemical method in small time
period. From the UV-VIS absorbance spectroscopy the band gap of the prepared material calculated is
found to be around 2.15 eV. Some physical parameters of the prepared material have also been calculated
from XRD and UV-VIS spectroscopy using some empirical relations. |
