Abstract

Indium tin oxide (ITO) nanoparticles were synthesized by green combustion method using indium (In) and tin (Sn) as precursors, and Carica papaya seed extract as novel fuel. This paper highlights the effect of tin concentration (5%, 10%, and 50%) on the microstructural, optical, and electrical properties of ITO nanoparticles (NPs). The indium nitrate and tin nitrate solution along with the fuel were heated at 600°C for 1 h in a muffle furnace and obtained powder was calcinated at 650°C for 3 h to produce ITO NPs. The above properties were investigated using XRD, FTIR, UV-Vis spectroscopy, SEM, TEM, and computer-controlled impedance analyzer. The XRD, SEM, and TEM investigations reveal the synthesized NPs were spherical in shape with an increase in average grain size (17.66 to 35 nm) as Sn concentration increases. FTIR investigations confirm the In-O bonding. The optical properties results revealed that the ITO NPs band gap decreased from 3.21 to 2.98 eV with an increase in Sn concentration. The ac conductivity of ITO NPs was found to increase with an increase in Sn concentration. These synthesized ITO NPs showed excellent properties for emerging sensor and optical device applications.

锡浓度对绿色法合成ITO纳米粒子的微观结构、光学和电学性能的影响

以铟（In）和锡（Sn）为前驱体，番木瓜籽提取物为新型燃料，采用绿色燃烧法合成了氧化铟锡（ITO）纳米粒子。本文强调了锡浓度（5%、10%和50%）对ITO纳米颗粒（NP）的微观结构、光学和电学性能的影响。将硝酸铟和硝酸锡溶液与燃料一起在马弗炉中在600°C下加热1小时，并将获得的粉末在650°C下煅烧3小时以生产ITO NP。利用XRD、FTIR、UV-Vis光谱、SEM、TEM和计算机控制的阻抗分析仪对上述性能进行了研究。XRD、SEM和TEM研究表明，随着Sn浓度的增加，合成的NP呈球形，平均晶粒尺寸（17.66至35nm）增加。FTIR研究证实了In-O键合。光学性能结果表明，随着Sn浓度的增加，ITO NPs的带隙从3.21eV减小到2.98eV。发现ITO NPs的交流电导率随着Sn浓度的增加而增加。这些合成的ITO NPs在新兴的传感器和光学器件应用中表现出优异的性能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
