Abstract
Abstract The samples prepared of ZnO powder with the addition of boric acid were sintered for 2 h in air at 1000 °C. The content of boric acid was varied from 0 to 15wt%. Electrical and luminescent characteristics of obtained ceramics were investigated in the 77–300 K temperature range. It was found that the addition of boric acid resulted in the rise of grain size, the increase of grain conductivity, the quenching of defect-related luminescence, and the enhancement of exciton emission.
