I have coated conductive glass with TiO2 using dip coating, the precursor I used was titanium butoxide, and I prepared 0.1 M solution with this precursor ( Propanol as solvent), the main problem is that even under various heat treatment ranges ( from 400 C for 2h to - 500 C for 24 h )I can not get anatase and the Raman spectra show the spectrum of the substrate only like there is no coating or no crystallinity. But the layer can be seen under SEM and the thickness is less than 100 nm.
Is there any suggestion on how to obtain anatase? Changing the precursor can help?
PS: I can not increase the annealing temperature to more than 500 C, because of the substrate.
Dear Mahsa Amiri, if you have ease in lab facilities, the following references worked at even lower temperatures. Please check the following documents. My Regards

Dear Abdelkader BOUAZIZ thanks for your reply, actually I want to stick to the sol-gel method.
No thanks, I think the third paper suits you best. Please also see the references theirin. Good Luck in your work
These are interesting documents to check them as well. My Regards
