Laser induced plasma studies on w mo and alloys of cu in air via time and space resolved libs and application in single line calibration free libs

Abstract

Laser Induced Breakdown Spectroscopy LIBS is an optical emission based technique used for qualitative and quantitative analysis for any sample In the present thesis time and space resolved LIBS are employed to study tungsten molybdenum and three different alloys of copper The plasma temperature estimated via Boltzmann plot method and stark broadened line is used to estimate the electron density The local thermodynamic equilibrium LTE and optical thin of plasma condition is verified in t...
