Abstract: Paper deals with the important question of the influence of plasma treatment on the luminescence properties of the ZnO nano- and microrods especially after the annealing in air at 700 ℃. The annealing in air at 700 ℃ significantly suppresses excitonic luminescence (it is practically vanquished). However, hydrogen plasma treatment makes the excitonic luminescence to raise up again surpassing the initial level of intensity in the as grown sample. The influence of Er content on this effect has been studied. Temperature dependence of the excitonic band has been measured as well on example of the Er doping level at 0.25%. Interestingly, hydrogen plasma treatment applied after the annealing in air at 700 ℃ had strong influence on the excitonic intensity of the photon energy distribution as a function of temperature. Moreover, the effect of annealing in air and subsequent hydrogen plasma treatment on the allowed infrared 1.54 μm erbium transition is quite opposite. Exposure to hydrogen plasma leads after the annealing in air at 700 ℃ to the about double reduction of the 1.54 μm erbium transition. This phenomenon practically does not depend on Er content.
