چکیده انگلیسی
Optical emission spectroscopic investigations of the plasma produced during Nd:YAG laser ablation of sintered TiO2 targets, in oxygen and argon gas environments are reported. The spatial variations of electron temperature (Te) and electron number density (Ne) are studied. The effect of oxygen/argon pressure on electron temperature (Te) and electron number density (Ne) is presented. The kinematics of the emitted particles and expansion of plume edge are discussed. Spatio-temporal variations of various species in TiO2 plasma were recorded and corresponding velocities were calculated. The effect of oxygen pressure on intensity of neutral/ion species and their corresponding velocities is also reported.
