The influence of thermal treatment and pressure of air on the parameters of radiation-induced defects in boron nitride modified by ions has been investigated using methods of thermo-activated and optical spectroscopy. The influence of the adsorption of oxygen on the type of dominating charge carriers, position of the Fermi level and character of optical, field and thermo-activated electron transitions has been found. The influence of electron transitions with the participation of the levels of the radiation-induced defects and complexes based on oxygen and the defects on the properties of the material has been determined in the framework of electronic models of the forbidden band.
