Titanium dioxide nanoparticles were produced in this work by laser ablation of a high purity titanium objective immersed in distilled water. Optical and structural properties of the obtained TiO2 NPs using a Q-switched Nd: YAG laser of 1064nm wavelength with different laser energy (80. 100. 120. https://www.lightemupsequences.com/limited-save-Custom-Congratulations-Banner-p4839-hot-choice/
