Optical properties of sprayed tin oxide films

الملخص EN

This research is intended to study the preparation of heat mirror by spray pyrolysis method.

Un-doped tin oxide (SnO2) and doped with 0.09 %, 0.9 %, and 9 %, titanium dioxide heat mirror films were deposited on pre-cleaned substrates.

The microstructure characterizations were carried out by x-ray diffraction technique.

The optical properties were obtained by UV-Visible spectrophotometer.

The un-doped samples have displayed average transmittance value of 73 % in the visible region.

Whereas, the doped samples of 0.09 and 0.9 mol % TiO2 show a good reflectance values of 76 % and 80 % respectively in the wavelength of 2700 nm.
