Abstract

In this work, Tio2 nanoparticles prepared by pulse laser
ablation(PLA) of titanium target (purity of 99.99%) immersed in methanol
solution by focused beam of 532 nm pulsed used Nd:YAG laser operating
at different laser pulses in range (1000, 1500, 2000) pulses with 1Hz
repetition rate, effective beam diameter 4.8 mm and 10 ns pulse width.
Laser energy was kept constant at (900) mJ. The effects of methanol
solution and number of laser pulses on the structural properties (XRD) and
morphology (FESEM) was study. From XRD measurment have been
revealed that 4peaks with 2? values of 27.160, 36.2, 54.7 and 69.02
degree, corresponding to TiO2 crystal planes of (110), (101), (211) and
(301) respectively at 2000 pulses in methanol solvent after heating at
temperature 85 oC for 45 minute.
