Paper Abstract

The influence of a weak magnetic field (H ~ 1 T) on the exciton radiation of the ZnO films covered with Ag island film was investigated at room temperature. It was found that there are some areas on these films where the several-percent enhancement of the exciton radiation intensity can be observed. The value of the enhancement slightly depends on the excitation level. At the same time there are other areas on the same films where the effect is negligible or absent. It is supposed that in the first case, magnetoexcitons are possibly formed due to the increase of the exciton momentum nearby an Ag nanoparticle. The probability of magnetoexciton recombination significantly increases even in a weak magnetic field due to the strong stretch of its wave function.
