    Posted: 08 April 2008 at 7:41am
Hello All,
Im making TiO2 films based on ethanol & Isopropanol & the thickness is around 100nm.
The films are also annealed at 450 & 600C.
Till now in around 3-4 trys ive failed to get XRD data of the as-deposited & of those annealed at 450C/600C.
XRD comes the same as that of the substrate ie glass/alumina.
Can anyone give me any inputs as to why is it happening so?
Some suggestions to get an XRD of the films?

Thanks in advance.

Hi,
May be the thickness of your film is not enough to get a good XRD pattern. In that case you can try grazing angle X-ray diffraction Or better increase the thickness of the film. Hope that will solve your problem.

Hi,

I agreed with pravin, my TiO2 thin film is about 17um, until now no problem to get the XRD result.

You should get XRD pattern if the film thickness is in micron. If not XRD machine may not be working properly or may be there problem in detector.

Thanks lot for your inputs,pravin & nano.
Think using Grazing Angle XRD should help.
Regarding the XRD machine,the spectrum itself has so many hills & valleys that it can get really tough to identify some small peaks if present.
Its not smooth to facilitate the same!
Will try with Grazing angle none the less.
