Proposed thermal evolution mechanism of IZO:F precursor solution.
(a) TGA data of the IZO:F, InF3 and ZnF2 dried precursor solutions. (b) Raman spectra (90–800 cm−1) were measured in the hydrolyzed IZO:F, InF3 and ZnF2 precursor solutions annealed for 1 hr at the indicated temperatures of 100°C(red line, ), 250°C(blue line,
) and 500°C(green line,
), respectively. The black line(
) is the InF3 and ZnF2 data at room temperature.
