Investigating the influence of spatial confinement on self-absorption effects in laser-induced breakdown spectroscopy

Key Points

• The aim is to understand how spatial confinement influences self-absorption effects in plasma emissions.
• Systematic examination of self-absorption effects
• Analysis of atomic and ionic emission lines
• Use of laser-induced breakdown spectroscopy (LIBS)
• Self-absorption behavior differs for atoms and ions under spatial confinement
• Spatial constraints significantly alter emission characteristics in LIBS plasmas
