Abstract
A method of synthesizing quantum dots includes adding titanium butoxide to isopropanol to obtain a first mixture. The method then includes adding distilled water to the first mixture to obtain a second mixture. The method then includes adding nitric acid to the second mixture to obtain a third mixture and stirring and heating the third mixture. The method then includes aging the third mixture at room temperature. The method further includes adding a cetyltrimethylammonium bromide (CTAB) solution to the third mixture to obtain a fourth mixture and stirring and treating the fourth mixture with heat to obtaining CTAB-TiO2 Quantum Dots (QD) (C-titania QDs).
