| Abstract: | The carrier recombination time and the diffusion coefficient of Cu2O ultrafine particles have been obtained at room temperature by take-delayed four-wave miaing with inCoherent light, being TR=1. 2 ns and D=0. 011 cm2/s. The method is verified by angle change experiment between the forward pump beam and the probe beam and the temperature varyins experiment. The diffusion Process is discussed. |

| Keywords: | carrier recombination time diffusion coefficient time-delayed four-wave mixing with incoheret light |
