“…This broadening is mainly attributed to the small size of CdSe NCs. In addition, the strong broad peak at 2h = 25.3°indicates that the growth direction is along the c-axis of the hexagonal lattice [26]. Figure 2 shows high resolution TEM images (a, b) together with SAED pattern (c) of the as-synthesized CdSe NCs.…”

Oleic acid (OA)-capped cadmium selenide (CdSe) nanocrystals (NCs) have been synthesized via a new high-scale route. X-ray diffraction and transmission electron microscopy confirmed that rod-like hexagonal (wurtzite) CdSe NCs with an average size of 10 nm were obtained via this new route. The obtained CdSe NCs were treated individually with pyridine and tert-butylamine (t-BA) for ligand exchange. Fourier transform infrared spectra of the as-synthesized and treated CdSe NCs confirmed the removal of OA ligands from the surface of CdSe NCs after treatments with pyridine and t-BA. Bulk-heterojunction (BHJ) solar cell devices were prepared using untreated and surface treated CdSe NCs blended with poly (3-hexylthiophene-2,5-diyl) (P3HT) polymer. BHJ solar cell devices made from P3HT:(surface treated CdSe NCs) blends showed greater improvement in photovoltaic performances compared to P3HT:(untreated CdSe NCs) blend. The improvement in photovoltaic performances was due to the increase of electron mobility in P3HT:(CdSe NCs) blends after surface treatment of CdSe NCs.

“…We aim to combine the advantages of good crystallinity with controlled growth using both these methods. We were surprised to note that when we followed our previous recipe to prepare CdSe nanoparticles [4], we found a mixture of spherical and hexagonal nanosheets. Possible reasons for this are as follows.…”

“…These methods include the hot coordination solvents method using tri-n-octylphosphine oxide (TOPO) and trioctylphosphine (TOP) [1], the hydrothermal or solvothermal method [2,3] and the micelle or reverse micelle method [4,5]. The electrical and optical properties of nanoparticles are affected by the chemistry involved in their synthesis.…”

“…They found that the concentration of CTAB is a key parameter in the control of nanoparticle morphology [3]. In our previous studies, we showed that at a moderate temperature (100 • C), with a combination of an anionic surfactant, sodium bis(2-ethylhexyl) sulfosuccinate (AOT) and a reducing agent, hydrazine hydrate, it is possible to control the morphology of the nanoparticles [4]. The mechanism for the formation of CdSe nanorods is the phase transition due to the addition of a very large amount of hydrazine hydrate to the reverse micelle solution during the reaction.…”

“…The formation of rod-like and fibre-like brushite nanomaterials is due to the confinement of the inorganic materials in the aqueous cores of sucrose ester microemulsion which have a prolate shape [46]. Furthermore, the low rate of brushite growth which is affected by the low reactant concentration [48] allows the confinement of brushite crystals in the water droplets of microemulsion. With higher W/S value, the length of the brushite particles became longer.…”

In the present study, 1-dimensional (1D) brushite nanomaterials were fabricated through sucrose ester based reverse microemulsion for the first time. X-ray diffraction patterns revealed that the nanomaterials possessed brushite crystal phase with trace amount of hydroxyapatite. The size and morphology of brushite crystals were governed by the changes in the aqueous-to-sucrose ester weight ratio at low initial reactant concentration, giving rise to rod-like and fibre-like 1D nanomaterials. Brushite nanorods and nanofibres with average diameters of 25.53 AE 4.60 nm (aspect ratio $ 6) and 76.18 AE 19.74 nm (aspect ratio $ 40), respectively, had been synthesized. As the reactant concentration increased, it became the key factor in controlling nucleation and crystal growth, rendering the aqueous-to-sucrose ester ratio unimportant. Formation mechanism of various morphologies of brushite crystals is postulated. #
