“…Several procedures and methods have previously been reported on the synthesis of ZnO NPs with the aim of improving the chemical and physical behaviours. Such include microwave assisted method [10], thermal evaporation method [11], thermal decomposition method [12], spray pyrolysis [13], chemical vapour deposition [14], hydrothermal growth [15], sol gel technique [16], precipitation method. Insipid that, most of these methods have difficulties in applying for large scale production due to the complicated procedure, high temperature involved, a longer period of reaction, toxic chemical reagent and by product release to the immediate environment at the end of the experiments.…”

A simple polymer synthesis was used to successfully synthesized Zinc Oxide Nanoparticles (ZnO NPs), and the influence of the different calcination temperature on the structural, and optical properties of the material was observed using several techniques. The formation of ZnO NPs was confirmed by FT−IR, EDX, XRD, FESEM and TEM images upon calcination from 500−750 °C. The FESEM images showed the ZNO NPs synthesized possessed a hexagonal shape and tended to become larger at higher calcination temperature. The XRD and FTIR revealed the precursor to be amorphous at room temperature but transform to a crystalline structure during the process of calcination. The crystalline and particle size increase as the temperature was increased. The crystalline size was between 24−49 nm for all samples calcined at 500−750 °C. The optical properties obtained by UV−vis reflectance spectrometer have further confirmed the formation of ZnO NPs. The band gap exhibits typical ZnO wide band gap, and the values decrease with an increase in calcination temperature.

“…Many elements have been selected as the dopant to obtain a more stable p-type ZnO semiconductor, such as N [ 20 , 21 ], P [ 22 ], As [ 23 ], Sb [ 23 ], Cu [ 24 ], Li [ 25 ], Na [ 26 ], Ag [ 27 ], and Au [ 28 ]. In addition, a multi-element co-dopant has also been used to improve the acceptor concentration [ 29 , 30 ] and to increase the whole concentration so as to compensate the intrinsic defect. But this makes the doping theory become complex.…”

Nitrogen-doped zinc oxide (N: ZnO) films have been prepared by oxidizing reactive RF magnetron-sputtering zinc nitride (Zn-N) films. The effect of oxidation temperature and oxidation time on the growth, transmittance, and electrical properties of the film has been explored. The results show that both long oxidation time and high oxidation temperature can obtain the film with a good transmittance (over 80 % for visible and infrared light) and a high carrier concentration. The N: ZnO film exhibits a special growth model with the oxidation time and is first to form a N: ZnO particle on the surface, then to become a N: ZnO layer, and followed by the inside Zn-N segregating to the surface to oxidize N: ZnO. The surface particle oxidized more adequately than the inside. However, the X-ray photoemission spectroscopy results show that the lower N concentration results in the lower N substitution in the O lattice (No). This leads to the formation of n-type N: ZnO and the decrease of carrier concentration. Thus, this method can be used to tune the microstructure, optical transmittance, and electrical properties of the N: ZnO film.
