We report on the comparative studies of linearly polarized photoluminescence (PL) in a ZnO epitaxial film and ZnO nanorods. At low temperatures the PL spectrum of both samples included a number of narrow lines attributed to donor‐bound excitons and a peak of free A excitons. An additional line observed in the nanorod sample was assigned to the excitons bound to some defects introduced during the sample post‐growth history and located near the nanorod tips. The emission of mixed longitudinal — transverse exciton polariton modes was observed at elevated temperatures in both samples.
