Abstract
â¶ Study of the picosecond vibrational dynamics of a series of metaphosphate glasses. â¶ The νs(PO2â) and νs(P-O-P) modes have been used as probes of the metaphosphate dynamics. â¶ The vibrational correlation functions comply with the Rothschild approach. â¶ The dispersion parameter evolution with cation radius indicates coherence decay reduction. â¶ Second moment variations imply alterations of repulsion/attraction forces between tetrahedra.
