Studies on synthesis of CdSe/ZnS nanoparticle base on ionic liquid

New aspects of ionic liquid was approched in applications where the semiconductor nanoparticles used as sensitizers of solar cells. The characterization of p6614 TFSI ionic liquid was analyzed and the effects of ionic liquid as capping ligand and/or solvent was studied on the morphology and phase of the CdSe/ZnS nanoparticles. Colloidal CdSe/ZnS nanoparticles were synthesized using a mixture of trihexyltetradecyl -phosphonium bis(trifluoromethyl sulfonyl) imide P66614 TFSI and octadecene(ODE). The CdSe/ZnS nanoparticles have a small size(5.5nm) and with a controled phase from zinc-blende to wurtzite by increasing the volume ration of P66614 TFSI.
