Difference Between Ito and Fto Coated Glass
April 5, 2017The transparent conductive oxide TCO used to make conductive coating over a glass or flexible sheet. TCO such as Indium tin oxide (ITO) Coated Glass, Fluorine-doped tin oxide (FTO), Aluminium-doped zinc oxide (AZO), Antimony-doped tin oxide (ATO) used to make conductive substrate. In research and industry mainly ITO and FTO coated glass used. Here are the following comparisons between ITO coated glass and FTO coated glass.
| ITO Coated Glass | FTO Coated Glass |
|---|---|
| · ITO coated glass can use maximum at 350 0C | · FTO coated glass coating works well on higher temperature 600 0C |
| · ITO Layer has medium transparency in visible light | · FTO surface is better transparent to visible light |
| · Resistance of ITO glass substrate increases with temperature | · Resistivity of FTO coated glass substrate is constant up to 600 0C |
| · ITO glass slides usability is suitable for inverted work | · FTO coated glass slides is rarely used for inverted work |
| · ITO coated glass plate has a lower thermal stability | · FTO coated substrate has an excellent thermal stability |
| · ITO coated sheets has moderate conductivity | · FTO coated surface has a good conductivity |
| · ITO coating is moderately tolerable for physical abrasion | · FTO layer is high tolerance to physical abrasion |
| · There is a passivation layer on the glass surface, then ITO coated on the passivation layer. | · FTO directly coated on glass surface |
| · ITO has a cubic structure in nature | · FTO consist tetragonal structure |
| · Average grain size of ITO is 257nm (SEM Result) | · Average grain size of FTO is 190nm (SEM Result) |
| · ITO has a lower reflectance in infrared zone | · FTO has a higher reflectance in infrared zone |
| · ITO glass is quite expensive | · FTO-coated glass is cheaper as compared to ITO glass. |
