Using the acetylacetonates of zinc and aluminium for the Metalorganic Chemical Vapour Deposition of aluminium doped zinc oxide films

Effects of Grain Size on the UV‐Photoresponse of Zinc Oxide Thin Films Grown by Spray‐Pyrolysis

“…It can be clearly observed that direct transmittance within the visible region is above 90% for the thinnest film, whereas it falls below 80% for the 415 nm film. A sharp absorption edge is observed, confirming the crystalline nature of films . The absorption edge shifts to blue with decreasing thickness, indicating wider optical band‐gaps for films with smaller grains.…”

“…A sharp absorption edge is observed, confirming the crystalline nature of films. [17] The absorption edge shifts to blue with decreasing thickness, indicating wider optical band-gaps for films with smaller grains. In addition, the number of oscillations due to interference effects produced at the film/substrate interphase also increases with film thickness.…”

“…Then, as far as the usual morphologies observed for ZnO nanostructures, [19,20] ZO20 and ZO30 films would be built up of hexagonal platelet-like grains, exhibiting mainly {0001} faces, rather than elongated structures or rods of hexagonal cross section. On the other hand, the changes observed in the relative intensities of planes (10-10), (10)(11), and (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) with respect to plane (0002) in the XRD pattern of film ZO40, show a different crystal morphology revealing an inversion in the anisotropy of grains. It seems that growing in the equatorial a and b directions is overtaken by a preferential growth in the c direction.…”

Aluminium/gallium, indium/gallium, and aluminium/indium co-doped ZnO thin films deposited via aerosol assisted CVD

“…Furthermore, aluminium has a relatively low toxicity compared to the other elements of group 13. 38 Additionally, AZO films tend to be more conductive than GZO and IZO films. [39][40][41] However, the high reactivity of aluminium may lead to unwanted side reactions during film growth.…”

Formation mechanisms of Fe3−xSnxO4 by a chemical vapor transport (CVT) process

“…A chemical vapor-transport (CVT) method is commonly used for obtaining high-quality single crystals that are difficult or even impossible to be prepared by other methods 22 23 24 25 . The CVT method was successfully applied for synthesizing various inorganic compounds and separating some rare metals and rare earths 26 27 28 29 . As an important preparative method in solid state chemistry field, a considerable amount of works were focused on the homogeneous gas-phase equilibria, the temperature dependency of heterogeneous reactions, the crystallization controlling conditions, and so on.…”
