Preparation and characterization of TiO2 NPs by PLAL technique.

In this paper, metal oxide nanoparticles (Titanium dioxide) were prepared by using laser ablation of titanium target immersed in deionized water, where we used the technique of laser ablation in the liquid (PLAL) because of its many advantages, including being a rapid and direct way to prepare NPs and do not require long and high reaction times, Temperature and high-pressure environment and its eco-friendly method. 0ptical and structural properties of the prepared TiO2NPs studied using Q-switched Nd: YAG laser with a wavelength of 1064nm with different energies (80, 100, 120, 140, & 160) mJ /100 pulses. In addition, the prepared TiO2NPs were characterized by UV-VIS and FTIR spectroscopies. The results showed that increasing the laser energy increases an absorbance of the prepared TiO2NPs, the energy bandgap (Eg) of the prepared TiO2NPs decreased with increased Laser energy. And from the FTIR results, the formation of TiO2NPs was confirmed and it has a bond at wavenumber ranging from (400-700 cm−1) [ABSTRACT FROM AUTHOR]
