“…Recently, different hydrothermal processes have been discussed in the literature for the synthesis of AZO nanostructures with high crystallinity at low reaction temperatures. 15,16 However, the obtained products usually are composed of nanoparticles with a broad size distribution and variations in morphology. Another promising strategy is the non-aqueous or solvothermal synthesis which has been proven capable of synthesizing a variety of metal oxides, resulting in high crystallinity, adjustable doping levels and narrow particle size distributions.…”

The non-aqueous sol-gel synthesis of aluminum zinc oxide (AZO) nanocrystals with controllable sizes and morphologies at comparatively low temperatures is presented. By varying the reaction chemistry, customized aluminum zinc oxide nanorods and nanospheres with adjustable composition and tailored morphology between 0-D and 1-D were obtained. We furthermore show that the band gap can be engineered by the Al content. Additionally, the growth kinetics and the influence of various process parameters such as the reaction temperature and precursor concentration as well as the scale-up from a 45 mL autoclave to a 500 mL reactor were investigated.Aluminum zinc oxide (AZO) nanocrystals with customized sizes and shapes were synthesized by non-aqueous reaction at moderate temperatures. The obtained morphology can be correlated with the solvent chemistry, with benzyl alcohol resulting in 1-D nanostructures whilst benzylamine leads to spherical nanoparticles.

“…The doping of ZnO with aluminum (Al) offers several advantages, such as high transparency, excellent conductivity, non-toxicity, and high mechanical/chemical stability that make this material ideal for TCO applications [ 7 , 21 ]. However, the doping concentration of Al needs to be carefully selected or optimized, as it can also decrease the electrical, structural, and optical properties of the AZO [ 50 , 51 , 52 , 53 ].…”

“…However, this low resistive film of AZO was prepared using magnetron sputtering [ 13 ], which increases its resulting cost. In this context, solution processable approaches, such as the use of sol-gel, [ 20 ] hydrothermal methods [ 21 ], etc., represents cost-effective and highly efficient methods to synthesize AZO. Beside the low-cost and easy tuning of the doping level, the solution processable route provides the possibility of synthesizing AZO in different morphologies, such as nanowires [ 22 ] nanorods [ 23 ] and nanoparticles [ 24 ], that can be beneficial for its application as a TCO.…”

With the continuous growth in the optoelectronic industry, the demand for novel and highly efficient materials is also growing. Specifically, the demand for the key component of several optoelectronic devices, i.e., transparent conducting oxides (TCOs), is receiving significant attention. The major reason behind this is the dependence of the current technology on only one material—indium tin oxide (ITO). Even though ITO still remains a highly efficient material, its high cost and the worldwide scarcity of indium creates an urgency for finding an alternative. In this regard, doped zinc oxide (ZnO), in particular, solution-processed aluminum doped ZnO (AZO), is emerging as a leading candidate to replace ITO due to its high abundant and exceptional physical/chemical properties. In this mini review, recent progress in the development of solution-processed AZO is presented. Beside the systematic review of the literature, the solution processable approaches used to synthesize AZO and the effect of aluminum doping content on the functional properties of AZO are also discussed. Moreover, the co-doping strategy (doping of aluminum with other elements) used to further improve the properties of AZO is also discussed and reviewed in this article.
