“…Since Sn act as donor in CuO, the carrier concentration will increase upon Sn doping which leads to band tail creation due to excessive donors. Such increase in band gap energy is previously reported for Ge and Sn doped ZnO nanostructures at higher doping levels [27,28].…”

“…The transmittance at 2 at.% Sn-doped ZnO thin film exhibited 96% average transparency, which was higher than that of the undoped and 1 at.% Sn-doped ZnO thin film. The high transmittance of thin film can be due to its small surface roughness, thereby suppressing the growth of ZnO Sn dopants and forming flat and fine surfaces [18]. Moreover, the obtained results are comparable with those obtained by Tsay et al [24] and Pan et al [26].…”

“…Yang et al [18] reported the influence of Sn-doping on ZnO nanorod prepared by hydrothermal method in aqueous solution using zinc nitrate as precursor; however, ZnO nanorods grown on Sn-doped ZnO as seed layers and applied in DSSCs are rarely reported. Moreover, Sn materials, which are originally from group IV elements, exhibit advantages because of their two more extra electrons that can be substituted into ZnO, thereby contributing to double charge carriers.…”

Aligned ZnO Nanorod arrays are deposited on the Sn-doped ZnO thin film via sonicated sol-gel immersion method. The structural, optical, and electrical properties of the Sn-doped ZnO thin films were investigated. Results show that the Sn-doped ZnO thin films with small grain size (~20 nm), high average transmittance (96%) in visible region, and good resistivity7.7 × 102 Ω·cm are obtained for 2 at.% Sn doping concentration. The aligned ZnO nanorod arrays with large surface area were also obtained for 2 at.% Sn-doped ZnO thin film. They were grown on sol-gel derived Sn-doped ZnO thin film, which acts as a seed layer, via sonicated sol-gel immersion method. The grown aligned ZnO nanorod arrays show high transmittance at visible region. The fabricated dye-sensitised solar cell based on the 2.0 at.% Sn-doped ZnO thin film with aligned ZnO nanorod arrays exhibits improved current density, open-circuit voltage, fill factor, and conversion efficiency compared with the undoped ZnO and 1 at.% Sn-doped ZnO thin films.

“…While in the visible region, it produces an optical transparency with a vast exciton binding energy of 60 meV. Nevertheless, ZnO is an n-type II-VI semiconductor and oxygen vacancies, zinc interstitials or complex defects are identified as principal donor centers [1,2]. Due to the fundamental properties ZnO possessed, it becomes an attractive material for various application such include extensive panel application in optoelectronics like photodetector [3], light emitting diodes (LED), and laser devices [4].…”

The influence of calcination temperature on structural and optical properties of ZnO nanoparticles via simple polymer synthesis route

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.
