Well-crystallized and nano-sized indium tin oxide (ITO) powders were prepared by a solvothermal process from a mixed solution consisting of indium nitrate and tin chloride. The characteristics of the solvothermally synthesized ITO powders were studied to investigate the contribution of the processing variables on the physico-chemical properties of powders. The results of this study show that the nano-sized blue ITO powders with a single phase could be directly obtained by changing the medium from water to organic solvent.

Indium tin oxide (ITO) nanoparticles (NPs) were prepared by a coprecipitation process from a mixed solution consisting of indium chloride and tin chloride. The surface plasmon resonance (SPR) absorption was studied under different calcinate atmospheres. The characteristics of the optical properties, especially the absorption of near-infrared (NIR) region was recorded by the UV-Vis-NIR absorption spectroscopy. The results show that the SPR absorption peak appears at 2500 nm under an oxidizing atmosphere (air) or at 1300 nm under a reducing atmosphere (a gas mixture of Ar and 5 vol% H2) when calcinated under a single atmosphere. There is no change in the plasmon frequency with the variance of calcinate temperatures and therefore no change in the free carrier concentration. However, when calcinated first at 600 °C under an oxidizing atmosphere and then reheated under a reducing atmosphere at different temperature, the SPR absorption peaks of the ITO NPs are at the range of from 1200 nm to 1430 nm, undergoing a blue shift as the reducing process temperature increases. The SPR absorption of the prepared ITO NPs is easily controlled by calcinate temperature under a process of calcination first under an oxidizing atmosphere and followed by under a reducing atmosphere.

In this study indium tin oxide (ITO) nanofibers were synthesized using an electrospinning method. The morphological properties of the ITO nanofibers were considered and their specific resistances were measured to determine their applicability as filler for a transparent conducting film. ITO/PVP composite nanofibers were successfully obtained by electrospinning using a precursor solution containing indium nitrate, tin chloride, and poly(vinlypyrrolidone). After the heat treatment of ITO/PVP composite nanofibers at 600 °C and 1000 °C, ITO nanofibers with an average diameter of about 168 nm and 165 nm were synthesized, respectively.

Abstract: Spinel ferrites with general formula AB2O4 possess charming magnetic and electrical properties owing to their thermal and chemical steadfastness. Spinel zinc ferrite (ZnFe2O4) nanoparticles have attracted massive attention due to their unusual amalgamation of properties, especially magnetic properties, where these properties are equipped as suitable candidates in the field of electronics. Here, a simple self-combustion technique is made with the assistance of albumen to synthesize nanocrystalline zinc ferrite (ZnFe2O4) particles. The egg white (albumen) that is used in the synthesis process plays the fuel role in the process of combustion. The results of the powder X-ray diffraction (PXRD) and Fourier Transform Infrared Spectroscopy (FTIR) suggested that the synthesized nanoparticles are of single phase and show spinel structure. The photoluminescence studies reported a doublet peak at around 360-380 nm. The functional groups present in the synthesized nanoparticles were revealed from FTIR data. EDX findings give an account of the percentage composition of the elements Fe, Zn and O present in the synthesized sample. High-resolution Scanning Microscope (HRSEM) reveals the agglomerated coalescence nature of ferrite nanoparticles. Keywords: Ferrite, PXRD, FTIR, HRSEM, EDX Albumen.

Uniform Size Distribution

In order to provide higher driving forces for densification of Indium-Tin oxide(ITO) sputtering targets, nano-sized ITO powders with uniform size distribution were prepared by solvothermal process. In this study, sintered bodies were densified by a spark plasma sintering (SPS) process at 950 oC. The experiments conduct the SPS method in order to achieve the highest density of sputtering targets. The phase and relative density of ITO sputtering targets were identified by X-ray diffractometry_(XRD) and Archimedes method, respectively. The surface microstructure and quanitative analysis of the targets were observed by scanning scanning electron microscopy (SEM), and ITO powders particle were measured by SEM, XRD-LB methods.
