Research output: Contribution to journalArticlepeer-review


The second-order nonlinear optical coefficient of polyphosphazene (PP)-based materials was analyzed by using ab initio methods. It was observed that the hyperpolarizability(β)/N value of PP converged quicly with chain length. It was also observed that sidegroups had little influence on the NLO response of long PP oligomers. It was suggested that nitrogen must be replaced by silica in order to increase β value of PP.
