Fluorine-Doped Tin Oxide Nanoparticles (FTO)

Product Overview

Fluorine-doped Tin Oxide (FTO) is an important transparent conductive oxide material. It is composed of tin oxide (SnO₂) doped with fluorine, offering excellent electrical conductivity, chemical stability, and high ultraviolet absorption. Fluorine doping significantly enhances the electrical and optical properties of tin oxide, making it widely applicable in solar cells, displays, gas sensing elements, and other fields. FTO, as a transparent conductive material, combines high transparency with low resistivity and maintains excellent performance under extreme conditions such as high temperature and acidity or alkalinity.

Key Features

• Low Resistivity: Fluorine doping significantly lowers the resistivity of tin oxide, improving its conductivity.
• High Chemical Stability: Fluorine doping enhances the chemical stability of tin oxide, increasing its resistance to acid, alkali, and atmospheric corrosion.
• Good Thermal Stability: FTO shows better stability in high-temperature environments compared to other transparent conductive materials.
• Strong UV Absorption: FTO has a high ultraviolet absorption coefficient, providing effective UV shielding.

Applications

• Solar Cells: FTO is widely used as a transparent electrode material in dye-sensitized and perovskite solar cells, significantly improving photovoltaic conversion efficiency.
• Displays: Used as a transparent conductive layer in LCDs and OLEDs, FTO provides pixel addressing and driving functions.
• Gas Sensing Elements: FTO thin films are used as the sensitive layer in gas sensors, effectively detecting harmful gases or volatile organic compounds (VOCs) in the air.
• Building Facade Glass and Transparent Windows: FTO thin films can be coated on building facades and transparent windows to provide conductivity, antistatic, and anti-fog functions.
• Other Applications: FTO is also used in sensors, digital displays, smart window coatings, catalyst supports, and more.
