Summary: | At room-temperature, a facile, seedless, and environmentally benign green route for the synthesis of star like PbS
nanoclusters at 7 min in aqueous solution of 1-ethyl-3-methylimidazolium ethyl sulfate, [EMIM] [EtSO4], room-temperature
ionic liquid (RTIL), via ultrasonic irradiation is proposed. The X-ray diffraction studies display that the
products are excellently crystallized in the form of cubic structure. An energy dispersive X-ray spectroscopy (EDX)
investigation reveals the products are extremely pure. The absorption spectra of the product exhibit band gap energy
of about 4.27 eV which shows an enormous blue shift of 3.86 eV that can be attributed to very small size of PbS
nanoparticles produced and quantum confinement effect. A possible formation mechanism of the PbS nanoparticles
using ultrasonic irradiation in aqueous solution of the RTIL is presented. KCI Citation Count: 23 |
