摘要：

Photoinduced spins with extended lifetime have been observed in hydrazone-polycarbonate dispersions. The presence of the spins changed the electrical characteristics of the dispersions. Measurements of electrical current associated with thermal equilibration after photoexcitation in dispersions of diethylamino-benzaldehyde diphenylhydrazone (DEH) in polycarbonate have been carried out. Sandwiched layers of the dispersions were excited with absorbed light. After withdrawal of the light, a voltage was applied and the current was measured. Experimental data provide evidence that photoinduced spins are derived from trapped carriers.
