摘要：

We present the results of the study of the nonlinear optical response observed in hybrid associates of Azure A dye with Zn0.5Cd0.5S colloidal quantum dots upon exposure to 10-ns pulses of the second harmonic (532 nm) of a Nd3+:YAG laser. It is shown that association enhances the absorption saturation in the dye by a factor of 4.5, which is caused by charge phototransfer between the components of the hybrid associate.
