Luminescence and ESCA analysis of laser-ablated materials

An investigation on laser-induced luminescence of simple solid oxides, their mixtures and other compounds is reported. Both a pulsed TEA CO, and a frequency-doubled Nd:YAG laser have been used. The luminous plume produced under the laser action by these compounds has been analyzed by an optical multichannel analyzer. The emission spectra show the presence of atomic, diatomic and more complex species. The ablated material was deposited on gold and SrTiO, substrates and analyzed by the ESCA technique.
