摘要：

Highly stable TiO2 sols were prepared by adjusting the water-to-titanium molar ratio to similar to 4 in the process of hydrolysis and condensation of titanium isopropoxide in ethanol with HNO3. Particularly, long-term stable TiO2 sols were prepared without adding any chemical additives. Anatase TiO2 nanocrystallites with sizes of 3-5 nm in diameter were uniformly dispersed in the stable sol. Crystallized TiO2 films were successfully deposited on Si (100) using the stable sol via a dip-coating process with low temperature curing at as low as 100 degrees C. The synthesized TiO2 sols and films are promising for use in flexible or dye-sensitized solar cells.
