Is Ito toxic?
If exposure is long-term, symptoms may become chronic and result in benign pneumoconiosis. Studies with animals indicate that indium tin oxide is toxic when ingested, along with negative effects on the kidney, lung, and heart.
What is Ito material?
Indium Tin Oxide (ITO, or tin-doped indium oxide) is a mixture of indium(III) oxide (In2O3) and tin(IV) oxide (SnO2), typically 90% In2O3, 10% SnO2 by weight. It is transparent and colorless when deposited as a thin film at thicknesses of 1000-3000 angstroms.
Is Ito brittle?
Compositionally, ITO is a ceramic, making it brittle and susceptible to cracking when flexed.
Is ITO organic?
Efficient indium-tin-oxide (ITO) free top-absorbing organic photodetector with highly transparent polymer top electrode.
Is ITO a dielectric?
Although the dielectric constant of silica is about 3.9 for capacitor applications at low frequencies, it drops to about 2.2 at the visible range or at high frequencies; the dielectric constant of ITO is 3.2, which is about 1.5 times higher than that of silica.
Is ITO amorphous?
The absence of ITO peaks on the X-ray diffraction patterns confirms the amorphous state of ITO films and the X-ray photoelectron spectroscopy spectrum validates the deposition of ITO films on the PLA substrate.
What is FTO substrate?
FTO (Fluorine-doped Tin Oxide) glass is a transparent conductive metal oxide that can be used in the fabrication of transparent electrodes for thin film photovoltaics, such as: organic photovoltaic, amorphous silicon, cadmium telluride, dye-sensitised solar cells, and hybrid perovskites.
Why is ITO used in OLED?
Indium tin oxide (ITO) has been widely used as a transparent electrode in most optoelectronic devices, including organic light-emitting diodes (OLEDs) [1, 2] . The high transparency in the visible region, high conductivity, and low sheet resistance of ITO make it as ideal candidate for electrode applications [3,4]. …
Is ITO conductive?
The ITO films are highly transparent (90.2%) and conductive (ρ = 7.2 × 10–4 Ω·cm) with the highest figure of merit (1.19 × 10–2 Ω–1) among all the solution-processed ITO films reported to date.
Is ITO crystalline?
XPS studies suggest that all the ITO films consist of crystalline and amorphous phases. The degree of crystallinity increases from less than 45% to more than 90% when the substrate temperature increases from 80 to 300 °C.
Why ITO is conductive and transparent?
ITO is not as conductive as metals, they do reflect light to, but this reflection only kicks in at longer wavelength (beyond visible light wavelength), therefore, they are transparent in the visible region.
Which is better FTO or ITO?
The transparent conductive oxide TCO used to make conductive coating over a glass or flexible sheet….DIFFERENCE BETWEEN ITO AND FTO COATED GLASS.
