Keywords: laser pyrolysis; nanoparticles; optical bandgap; Zn/F-doped SnO2; Introduction Recently, there has been growing interest in the field of transparent conducting oxides and wide bandgap oxide nanocrystalline materials such as tin oxide (SnO2). It is generally agreed that

• /DZnEt2, while keeping the sensitizer flow constant. In order to estimate the elemental composition for the Zn/F-doped SnO2 powders, EDX and XPS measurements were conducted; the results are presented in Table 1. In the XPS measurements, the peaks centered around 487 eV, 494 eV, 531.43 eV, 684 eV, 1022 eV

•  3a, a high-resolution TEM (HRTEM) image of a Zn/F-doped SnO2 sample (labeled ZTO0.44) and its mean size distribution (inset in Figure 3a) are presented. The polyhedral crystalline tin dioxide aggregated nanoparticles can be clearly seen in the HRTEM image. Also, a very thin disordered layer can be
