A single-source route to CdS nanorods

Abstract

We report the preparation of CdS nanorods using a thiosemicarbazide complex of cadmium [Cd(NH2CSNHNH2)2Cl2]. The precursor was decomposed in tri-n-octylphosphine oxide (TOPO) at 280 degrees C to give TOPO capped CdS nanoparticles; nano-dimensional rods of the material are clearly visible in transmission electron microscopy (TEM); the particles have been further characterised by X-ray diffraction (XRD) and selected area electron diffraction (SAED) and optical measurements.

Growth of photoluminescent Ag2Se nanowires from a simple precursor solution

“…[1][2][3][4][5][6][7] As a promising class of A I 2 B VI semiconductors, silver selenide (Ag 2 Se) nanocrystals such as nanodots, 8 nanofibers/nanowires 9,10 and nanodendrites 11 are actively studied due to their unique optical properties, thermoelectric properties and controlled preparation. 10,[12][13][14] 1D nanostructured materials are desirable functional or connecting elements in the fabrication of nanoscale devices with substantial applications in electronics and photoelectronics.…”

“…[29][30][31][32] Analysis on various stibnite and bismuthinite samples from various localities show that replacement of Sb with Bi goes up to 55 moles% giving a limiting mixability range of (Bi 0.45 Sb 0.55 ) 2 S 3 in naturally occurring Bi 2 S 3 -Sb 2 S 3 solid solution. 25,32,33 This paucity of representation covering the whole solid solution range in natural samples is attributed to the different geological conditions under which bismuthinite and stibnite are deposited in nature. 25,34 Kyono et al synthesised a full range (BiSb) 2 S 3 solid solution series with a nearly statistical substitution of Sb for bismuth by heating Bi 2 S 3 and Sb 2 S 3 at 800 to 1000 C. 30 However, their method provided no control over stoichiometry as four samples with the same composition range were obtained from a starting mixture with the same Bi 2 S 3 : Sb 2 S 3 molar ratio.…”
