Rapid phosphine-free growth of diverse CdSe multipods via microwave irradiation route

Hydrothermal synthesis and characterization of novel PbSe dendritic structures

“…Narrow-band gap IV-VI group semiconductors such as PbS, PbSe, CdSe and PbTe provide unique properties for investigating the effects of strong confinement on electrons and phonons [1,2]. PbSe can be potentially employed in various areas, such as laser materials, solar cells, infrared detectors [3,4], near-IR luminescence [5], photographic planes, selective, photovoltaic absorbers [6] and thermoelectric devices [7].…”

A facile microwave solvothermal process to synthesize ZnWO4 nanoparticles

“…Therefore the utilization of microwave has been a focus. This process has been employed to synthesize various compounds such as CaWO 4 , SrWO 4 [22], BaWO 4 [23], Bi 2 WO 6 [24], hydroxyapatite nanostrips [25], SrMoO 4 [26], CdSe [27], ZnS:Mn 2+ nanoparticles [28], ZnO [29], CeO 2 [30], Zn 2 SiO 4 [31], LaFeO 3 [32], BaMgAl 10 O 17 :Eu 2+ [33], Mg 2 NiH 4 [34], Ni-Zn-Sm ferrites [35] and so on.…”

Synthesis of CdSe micro/nanocrystals with controllable multiform morphologies and crystal phases

“…In some previous reports, it was pointed out that CdSe multipods with a high yield was difficult to obtain because the energy difference between the zinc blende and wurtzite structures is too small to facilitate controllable tetrapod-shaped nanocrystal synthesis [16]. Researchers have also proposed that various shapes and structures of nanocrystals could be controlled by the type of caping agents added [21,29]. But our results revealed that the Cd sources have a good selectivity to the formation of multi-foots rods.…”

“…To date, many studies have focused on improving methods for controllable synthesis of CdSe micro/nanocrystals, such as changing the species and concentrations of the capping agents, reducing agents or reaction temperature. Multiform CdSe micro/nanocrystals including wires [11], rods [12,13], tubes [14], quantum dots [15], tetrapods [16], hollow spheres [17] and hyper-branched structures [18][19][20][21] were demonstrated. In addition, CdSe phase transition from zinc blende to wurtzite has also been observed [22].…”

“…Recently, diverse multipod-shaped CdSe nanocrystals were achieved via microwave irradiation route. By selectively introducing typical organic ligands (such as CTAB and PVP), the morphologies of CdSe crystals could vary from tetrapods to more complex multipods [21]. However, it is also a challenge to synthesize CdSe micro/nanocrystals with controllable multiform morphologies.…”
