摘要

Titanium dioxide (Ti02) forms the basis of devices for applications including sensing devices, solar cells, photo-electrochromics, and photocatalysis. Such devices exploit different phases of Ti02 within such devices and accordingly it would be beneficial to have an amorphous Ti02 precursor which allows crystalline phase spatial patterning, for the crystallization of the amorphous Ti02 precursor to be triggered at low energies, and with the crystalline phase controllable at room-temperature without necessitating complex handling whilst providing Ti02 phases that are stable over a prolonged period of time. Accordingly, there are provided processes for providing a Ti02 precursor and controlling the conversion of the Ti02 precursor from amorphous-to-anatase, amorphous-to-rutile, amorphous-to-mixture of anatase/rutile or from amorphous-to-anatase-to-rutile in a simple and efficient manner.
