Abstract
Raman spectroscopy has been applied to probe the local oxygen arrangements before, during, and after laser irradiation. During annealing the structure can be described as the high-temperature T′ phase inlaid with ordered domains. The phase separation reported earier for the case δ ∼ 0.5 is found to take place over the whole 0 < δ < 1 range at room and low temperatures. The main Raman phonon bands contain a superposition of Ortho-I, Ortho-II and T components. The variations of the Raman mode intensities of the Ortho-I, Ortho-II and T modifications with laser irradiation dose follow the expected changes of relative weight of the corresponding microphases. Additional Raman bands that become strongly enhanced during annealing are assigned to vibrations of Cu(1) and O(1) atoms beloning to Cu(1) n+1 O(1) n ( n = 1, 2,3.) chain fragments.
