The Difference Between ITO and FTO Glass
Do you know the difference between ITO and FTO glass?
Indium tin oxide (ITO) coated glass, Fluorine-doped tin oxide (FTO) coated glass are all part of transparent conductive oxide (TCO) coated glass. It mainly used in Lab, research and industry.
Here find the comparisons sheet between ITO and FTO glass:
| ITO Coated Glass |
| · ITO coated glass can use maximum at 350 °C without big change on conductivity |
| · ITO Layer has medium transparency in visible light |
| · Resistance of ITO glass substrate increases with temperature |
| · ITO glass slides usability is suitable for inverted work |
| · ITO coated glass plate has a lower thermal stability |
| · ITO coated sheets has moderate conductivity |
| · ITO coating is moderately tolerable for physical abrasion |
| · There is a passivation layer on the glass surface, then ITO coated on the passivation layer. |
| · ITO has a cubic structure in nature |
| · Average grain size of ITO is 257nm (SEM Result) |
| · ITO has a lower reflectance in infrared zone |
| · ITO glass is cheaper as compared to FTO glass |
| FTO Coated Glass |
| · FTO coated glass coating works well on higher temperature 600°C without big change on conductivity |
| · FTO surface is better transparent to visible light |
| · Resistivity of FTO coated glass substrate is constant up to 600°C |
| · FTO coated glass slides is rarely used for inverted work |
| · FTO coated substrate has an excellent thermal stability |
| · FTO coated surface has a good conductivity |
| · FTO layer is high tolerance to physical abrasion |
| · FTO directly coated on glass surface |
| · FTO consist tetragonal structure |
| · Average grain size of FTO is 190nm (SEM Result) |
| · FTO has a higher reflectance in infrared zone |
| · FTO-coated glass is quite expensive . |
