A comparative study of the synthesis of CdO nanoplatelets by an albumen-assisted isothermal evaporation method

Influence of Strong and Weak Alkaline Medium on Microstructural and Morphological Investigation of Surfactant Based Synthesis of CdO Nanorods

“…3a&c), this quick change of vibration demonstrate that the weak alkaline medium (pH=9.0) does not support the complete formation of spherical nano particle, however while using strong alkaline medium in presence of 0.1M NaOH (pH=11.0) the particles are transformed to nanorod shaped particles. When pH value increases in presence of of 0.1M NaOH, the vibration peak of C=O was moved up and down which is also due to the morphological changes observed from TEM images and the symmetric stretching take place 1192 cm -1 to 860 cm -1 [27,9]. This is mainly due to the step-by-step removal of hydrated water molecules from the intermediate complex by OHions from sodium hydroxide.…”

“…As the energy band gap is known to increase as particle size of the semiconductor nanomaterials decreases, the higher value of band gap recorded for the NH4OH samples is a confirm of the presence of nanostructures of reduced size [8]. medium sample, the formed agglomerates are somewhat thicker and this hinders the radiation to diffuse towards the surface, which resultsin a decrease in the intensity of the blue emission peaks [31,9].…”

“…By vapour phase transport, solvothermal methods, microemulsion and template-assisted, CdO nanostructures can be synthesized [9,10]. These methods, however, require high temperatures, huge investments, multi-step development, sophisticated facilities for instruments, etc [11,12].…”

The Impact of Polyvinylpyrrolidone on Properties of Cadmium Oxide Semiconductor Nanoparticles Manufactured by Heat Treatment Technique

“…There are a number of methods whereby CdO nanomaterials can be produced. They include, but are not limited to, the sonochemical technique [ 54 ], the solvothermal method [ 55 ], the sonochemical process [ 56 ], heat based decomposition [ 57 ], the soft chemical process [ 58 ], the evaporation technique [ 59 ], and more. Yet, the efficiency of each technique for distributing nanoparticles is restricted by re-accumulation of the separate nanoparticles and the development of an equipoise environment within certain situations, which dictates the dimension levels of the agglomerate of distributed nanoparticles.…”

Structural, morphological and optical behaviour of PVP capped binary (ZnO)0.4 (CdO)0.6 nanoparticles synthesised by a facile thermal route

“…In a similar way to the ZnO semiconductors, many different forms of CdO have been created at the nanoscale, such as cubes [64], thin films of nanoclusters [65], wires [66,67], nanoclusters [68], nanoparticles [69][70][71], crystals [72,73], nanorodes [74] and several more exotic structures such as CdO Rhombus-like nanostructure [75] and heterojunction nanofibres [76], among others [77]. The range of processing techniques applicable to CdO semiconductors mirrors those of ZnO, for example sonochemical and solvothermal processes [78], thermal decomposition [79], soft chemical methods [80], and evaporation techniques [81]. Zn x Cd 1 À x O composite material has been produced using several methods, with the assistance of both spontaneous and piezoelectric polarisations of the internal electric field [82,83].…”
