However, by controlling the reaction conditions, we found that the structure and composition of the CZTSe nanocrystals (NCs) can be tuned. This can be achieved by using a simple hot injection approach. The structural properties of the CZTSe NCs were characterized by powder X-ray diffraction (PXRD), Raman spectroscopy and transmission electron microscopy. The energy dispersive X-ray spectroscopy confirms the stoichiometry of CZTSe NCs. The optical band gap of the NCs is found to be around 1.38 eV, as estimated from UV-Vis absorption spectroscopy. PXRD studies show that the obtained CZTSe NCs occurring in three structurally different phases (tetragonal kesterite type, hexagonal wurtzite type and orthorhombic wurtz-stannite type) are converted to the kesterite structure by annealing at 540 °C for 30 min under an Se-vapour atmosphere.","5 S.","29358","https://refubium.fu-berlin.de/handle/fub188/17170||http://dx.doi.org/10.17169/refubium-21348","eng","http://www.rsc.org/AboutUs/Copyright/Authordeposition.asp","500 Naturwissenschaften und Mathematik::530 Physik","Synthesis of Cu2ZnxSnySe1+x+2y nanocrystals with wurtzite-derived structure","Wissenschaftlicher Artikel","open access","RSC Advances. - 2 (2012), 26, S. 9894-9898","10.1039/c2ra21293e","http://dx.doi.org/10.1039/c2ra21293e","2046-2069","Institut für Experimentalphysik:::0e15dd66-95f1-40d5-8307-e68203f86a76:::600","Physik","FUDOCS_derivate_000000003815","FUDOCS_document_000000020796","no"
