Physical and Chemical Properties of Antimony Tin Oxide Nanoparticles

What is ATO?

Antimony-doped tin oxide (ATO) nanoparticles have been proven to exhibit special optical properties and excellent electrical conductivity to be used as thin film electrodes. Studies have shown that antimony-doped tin oxide possesses a high n-type electric performance. It is employed in the form of the traditionally produced aerogel thin films to collect electrons in solar cells. Introducing antimony to the tin oxide structure can significantly increase the electron conductivity making it an excellent conductive material. Antimony tin oxide is transparent in the entire region of visible electromagnetic light, whereas it reflects infrared light. Generally, the majority of the research projects concerning ATO have concentrated on the thin films of antimony-doped tin oxide, no matter whether they are made of nanoparticles or from particular precursors directly.

 

Physical and Chemical Properties of Antimony Tin Oxide Nanoparticles

ATO nanoparticles have attracted significant attention due to their well-known infrared light insulation quality, electrically conducting oxide, and optical transparency. Antimony as the n-type dopant of tin oxide (SnO2) modifies the band structure of the tin oxide. Extra electron donation to the conduction band upon a substitutional cation replacement is carried on via a dopant as an impurity. The band structure of antimony-doped tin oxide shows analytical data of the Sb-5s-like band in the tin oxide's band gap by a characteristic free electron at the G point. Additionally, it is elicited that this band gap is a half-filled metallic ion with extra thermal excitation into bands similar to those of tin capable of increasing the conductivity 1. Antimony, which is the doped agent in antimony tin oxide, has two ionic states based on its two valence electrons as Sb3+ and Sb5+ with a feasible switch Sb3+↔Sb5+ regarded as the redox enzymes catalytic cycle analog in which the metal ions serve as cofactors to promote the possible reversing redox reactions against intracellular oxidizing agents.

 

Synthesis and Preparation of Antimony Tin Oxide Nanoparticle

Considering the predominant applications of antimony tin oxide nanoparticles, numerous methods and techniques have been introduced to obtain them. It has to be taken into consideration that the properties of ATO are influenced by the synthesis and preparation process. The goal is always to obtain crystals with controlled size and an appropriate monodispersity to achieve high-performance material. On the contrary, synthesizing antimony tin oxide nanoparticles is still challenging, combining all the required standards and determining factors like adequate conductivity, desirable particle size crystallinity, narrow particle size distribution, and favorable dispersibility in a particular solvent. The most common and known methods include simple thermal evaporation, microemulsions, sol-gel, hydrothermal methods, co-precipitation, mechanochemical, laser ablation, screen printing, combustion route, microwave-assisted synthesis, thermal decomposition, hot injection, and DC arc plasma jet synthesis.

 

Price of ATO

ATO particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of ATO. A large amount of large amount will be lower. The Price of ATO is on our company's official website.
