Paper Abstract

An appearance of the photoluminescence anisotropy induced by photochemical reaction under continuous irradiation with polarized light is demonstrated for an ensemble of CdSe/ZnS quantum rods chaotically embedded in the pores of filter paper. A specific relaxation of the photoinduced anisotropy is revealed in darkness after an extended period of irradiation. This process is attributed to rotational diffusion of the nanocrystals in the pores of filter paper. The suggested theoretical model is used to estimate the rotational diffusion constant D , which is calculated to be 9.7×10 −3s−1 for the sample after 5 h of irradiation.
