The effects of methanol<br>solution and number of laser pulses on the structural properties (XRD) and<br>morphology (FESEM) was study. From XRD measurment have been<br>revealed that 4peaks with 2? values of 27.160, 36.2, 54.7 and 69.02<br>degree, corresponding to TiO2 crystal planes of (110), (101), (211) and<br>(301) respectively at 2000 pulses in methanol solvent after heating at<br>temperature 85 oC for 45 minute.</p> ER -
