Two dimensional Phase-selective LIBS

Two-dimensional imaging of gas/particle phase transition of metal   oxides in their native high-temperature flow conditions, using  laser-driven localized nanoplasmas, was obtained by utilizing the gap between the excitation energies of the gas and particle phases such that only the Ti atoms in the particle phase were selectively excited without detectable Bremsstrahlung background.
