“…The grain size is evaluated from AFM image which increase from 23.4 to 58.5 nm with increasing the film thickness from 52 to 136 nm. This parameter nearly matches with calculated from the XRD measurements in our previous work, as seen in Table . The root mean square (RMS) values of the surface roughness of the films are shown in Fig.…”

“…TCO thin films should have both good optical transparency and electrical conductivity to develop better performance optoelectronic device applications. In our previous work, the transparency and conductivity properties of AZO/ITO/PET structure depend on the AZO thin film thickness which is presented in this work have been detailed investigated . Our results have shown that the coating has not strongly affected on the optical transmittance and sheet resistivity.…”

“…As well known, the optical properties of the AZO thin films are affected by the microstructure of the films . In our previous work, we have investigated the structural properties of the AZO thin films depending on the film thickness, using X‐ray diffractometer . With increasing the film thickness, the crystalline quality has been improved, and the grain sizes became larger.…”

“…AZO/ITO/PET structures have improved device efficiency compared to single‐layer TCO electrode, owing to better electrical conductivity and mechanical stability. In addition, the optical transmission which is the most important parameter for optical devices is increased by coating of AZO thin films on the ITO . However, surface morphological and emission properties of deposited high quality AZO thin films on ITO coated flexible PET substrates have not been sufficiently investigated in the literature.…”

Al-doped zinc oxide (AZO) thin films were deposited on indium tin oxide (ITO) coated polyethylene terephthalate (PET) substrates by radio frequency (RF) magnetron sputtering method at room temperature. The effects of film thickness on the surface structure and the photoluminescence properties of the films were investigated by atomic force microscopy (AFM), secondary ion mass spectroscopy (SIMS) and room temperature photoluminescence (PL). AFM analysis showed that the surface of all films was extremely flat and uniform at nanoscale. Root mean square (RMS) value of the surface roughness which scanned the surface area of 3 μm by 3 μm and grain size increased with increasing the film thickness. Thus, the surface morphology of the films became rough because of the coarse grains. The depth profile of AZO layers was analyzed by SIMS. It was found that the thickness of the AZO layer is almost same with the desired film thickness. The PL intensity of the dominant peak decreased and shifted slightly towards the shorter wavelengths with increasing the film thickness. According to the relationships between luminescence intensity and crystalline characteristics, it was observed that the intensity of the peak decreased by the increased surface area of the grains.

“…Furthermore, ZnO is an attractive material for short wavelength optoelectronic applications because of its large exciton binding energy (60 meV) and the possi bility of tuning the band gap by doping or alloying with some metals like aluminum (Al), boron (B), gallium (Ga), indium (In) andmagnesium (Mg) etc. Al is widely used as dopants in most researches based on ZnO [4][5][6], but if it presents a high reactivity, it may lead to oxidation during the growth of the films. Therefore, as an alternative, it is possible to use of Ga which is less reactive and more resistant to oxidation compared to Al [7].…”

The ZnMnO thin films were deposited on glass substrates by radio frequency magnetron sputter ing method. The properties of ZnMnO thin films were investigated by high resolution x ray diffractometer (HRXRD),atomic force microscopy (AFM), UV-Vis spectrometer and room temperature photolumines cence (PL), under the influence of substrate temperature. The substrate temperature was varied from 300, 400 and 500°C. With increasing the substrate temperature, the structure of the films changed from cubic to hex agonal. The cubic ZnMnO thin films grown along [210] direction, while the hexagonal ones grown along [002] direction. The changes in surface morphology provided a proof on the structural transition. Also, decrease and increase of optical band gap is associated with cubic or hexagonal structure of the films.

Production and Photoelectric Activity of P and Al Co‐Doped ZnO Nanomaterials

Materials that have both conductivity and photocatalytic activity are widely applied in electrical devices and as environmental pollution handles. Based on such requirements, phosphorus and aluminium co-doped conductive zinc oxide nanocrystals (PAZO NCs) with novel visible-light catalytic activities have been mass produced by the combustion method. The PAZO NCs have diameters of 30-100 nm and BET specific surface areas of 15.27-18.99 m 2 g -1 . These PAZO NCs exhibited novel photocatalytic activity and good conductivity [the powder conductivity was (0.98-1.76) ϫ[a] 3708 10 -4 S cm -1 ], the reason being mainly attributed to the increase in carrier concentration and defects through P and Al co-doping. In addition, we found that the 3PAZO NCs, in which the molar ratio of Zn to P atoms is 100:3, had the best visible-light catalytic efficiency of the PAZO NCs, and the size of PAZO NCs decreased with increasing doping of phosphorus and aluminium. This study is useful as a reference for the mass production of modified ZnO NCs and its applications, such as in environmental management, photocatalysis, and anti-static electricity.
