英文摘要	a simple one-pot method is developed to prepare size-and shape-controlled copper(i) sulfide (cu2s) nanocrystals by thermolysis of a mixed solution of copper acetylacetonate, dodecanethiol and oleylamine at a relatively high temperature. the crystal structure, chemical composition and morphology of the as-obtained products are characterized by powder x-ray diffraction (pxrd), x-ray photoelectron spectroscopy (xps), auger electron spectroscopy (aes), transmission electron microscopy (tem) and scanning electron microscopy (sem). the morphology and size of the cu2s nanocrystals can be easily controlled by adjusting the reaction parameters. the cu2s nanocrystals evolve from spherical to disk-like with increasing reaction temperature. the spherical cu2s nanocrystals have a high tendency to self-assemble into close-packed superlattice structures. the shape of the cu2s nanodisks changes from cylinder to hexagonal prism with prolonged reaction time, accompanied by the diameter and thickness increasing. more interestingly, the nanodisks are inclined to self-assemble into face-to-face stacking chains with different lengths and orientations. this one-pot approach may extend to synthesis of other metal sulfide nanocrystals with different shapes and sizes.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-18t13:48:18z no. of bitstreams: 1 one-pot synthesis and self-assembly of colloidal copper(i) sulfide nanocrystals.pdf: 3189974 bytes, checksum: 920e3eabb710a8d560336921dc067405 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-07-18t13:55:57z (gmt) no. of bitstreams: 1 one-pot synthesis and self-assembly of colloidal copper(i) sulfide nanocrystals.pdf: 3189974 bytes, checksum: 920e3eabb710a8d560336921dc067405 (md5); made available in dspace on 2010-07-18t13:55:58z (gmt). no. of bitstreams: 1 one-pot synthesis and self-assembly of colloidal copper(i) sulfide nanocrystals.pdf: 3189974 bytes, checksum: 920e3eabb710a8d560336921dc067405 (md5) previous issue date: 2010; this work was partly supported by nsfc projects (60954001, 60825407, 60736034 and 50990064), '973' projects (2010cb933800), the program for ncet (08-0717), and the '111' project (b08002). awt is also grateful to the china postdoctoral science foundation and the foundation from the key laboratory of luminescence and optical information (beijing jiaotong university), ministry of education.; 国内
