摘要：

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 (T-e) and electron number density (N-e) are studied. The effect of oxygen/argon pressure on electron temperature (T-e) and electron number density (N-e) 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. (C) 2009 Elsevier B.V. All rights reserved.
