microcrystallite-doped glasses with 10-45Å size particles are successfully prepared.Transmission electron microscopy has been used to observe the microcrystallite structure and morphology characteristics in glasses.The third-order nonlinear susceptibility and plasma recombination time of the glass is measured by Four-wave mixing technique.The results showed x
