本文首次报道了制备高结晶度单晶透明导电氧化物（TCO）纳米粒子的一般方法：锡掺杂氧化铟（ITO）、锌掺杂氧化铟（IZO）、铝掺杂氧化锌（AZO）和镓掺杂氧化锌（GZO）。采用改进的雾化器和预热的载气进行低压喷雾热解。系统研究了热解压力、热解温度和载气温度对TCO纳米粒子尺寸和形貌的影响。合成的TCO纳米颗粒为17 nm大，微晶尺寸为8-11 nm。测量并比较所形成的粒料的结晶度。这些结果表明，该方法成功地生产了各种TCO纳米粒子，既不使用分散剂，也不使用后加热处理，这允许快速，连续，单步制备。(C)2008年，日本粉末技术学会。由Elsevier BV和日本粉末技术协会出版。All rights reserved.
In this article, we firstly reported a general preparation method for the production of highly crystallized and single crystalline transparent conducting oxide (TCO) nanoparticles: tin-doped indium oxide (ITO), zinc-doped indium oxide (IZO), aluminum-doped zinc oxide (AZO), and gallium-doped zinc oxide (GZO). Low-pressure spray pyrolysis was applied by means of a modified-atomizer and preheated carrier gas. The effects of pyrolysis pressure, temperature and carrier gas temperature on the size and morphology of the synthesized TCO nanoparticles were systematically investigated. The synthesized TCO nanoparticles were 17 nm large with crystallite size of 8-11 nm. The resistivities of the formed pellets were measured and compared. These results showed that this method successfully produces various TCO nanoparticles using neither dispersing agents nor post-heating treatments, which allows rapid, continuous, single-step preparation.
