Senthil Department of Physics, Erode Sengunthar Engineering College, Erode, Tamilnadu, India Journal Article 2013 09 04 Titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. Titanium isoprophoxide and absolute ethanol were used as precursors to prepare the sol. The pH of the solution was adjusted by adding nitric acid and sodium hydroxide solution. The prepared TiO₂ nanocrystals were annealed at 325°C, 425°C and 525°C respectively. The effect of pH on the surface morphology and structural properties of TiO₂ nanocrystals were studied. https://ijsts.shirazu.ac.ir/article_1999_4426dd8b0e3cf6988050f2c7fee962c7.pdf
