چکیده
in this paper, indium tin oxide (ito) nanoparticles has been prepared by chemical methods under given conditions with solution of indium chloride (incl3·4h2o), tin chloride (sncl4·5h2o) in ammonia solution. the samples were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem) analyses after heat treatments. the sem results showed that, the size of the ito particles prepared by co-precipitation route decreased to 46 nm whereas the size of the ito prepared by hydrothermal and pechini sol-gel methods increased to 1 micron. the xrd patterns revealed that, the size of crystallite ito particles prepared by sol-gel and hydrothermal methods increased. finally the intensity ratio of i400/i222 had a decrease of 21.67 percent for ito prepared by hydrothermal method.

متن کاملEfficiency improvement in InGaN-based solar cells by indium tin oxide nano dots covered with ITO films.
InGaN based MQW solar cells have been fabricated with 4 different transparent top electrode structures: (1)- ITO 200 nm, (2)-ITO nano dots only, (3)-ITO nano dots on ITO 50 nm and (4)-ITO nano dots on ITO 100 nm. The solar cell with the ITO 50 nm on ITO nano dots under AM 1.5 conditions showed the best results: 2.3 V for V(oc), 0.69 mA/cm(2) for J(sc), 41.8% for peak EQE, and 0.91% for conversi...
متن کاملFunctionalization of indium tin oxide.
The preparation and functionalization of ITO surfaces has been studied using primarily X-ray photoemission spectroscopy and infrared reflection-absorption spectroscopy (IRRAS) and the reagents n-hexylamine and n-octyltrimethoxysilane (OTMS). Particular attention has been paid to characterization of the surfaces both before and after functionalization. Surfaces cleaned by ultraviolet (UV)/ozone ...
متن کاملSynthesis of a Nonagglomerated Indium Tin Oxide Nanoparticle Dispersion
The importance and use of transparent conducting oxides (TCOs) has grown significantly over the last decade. The most successful of these materials is tin-doped indium oxide (ITO), which can be found in a wide variety of applications including flat-panel displays, functional glass, solar cells, and lightemitting diodes. When deposited as a thin film, the conductivity of an ITO layer commonly re...
متن کاملBroadband terahertz conductivity and optical transmission of indium-tin-oxide (ITO) nanomaterials.
Indium-tin-oxide (ITO) nanorods (NRs) and nanowhiskers (NWhs) were fabricated by an electron-beam glancing-angle deposition (GLAD) system. These nanomaterials are of interests as transparent conducting electrodes in various devices. Two terahertz (THz) time-domain spectrometers (TDS) with combined spectral coverage from 0.15 to 9.00 THz were used. These allow accurate determination of the optic...
