The peculiarities of hydroxyl impurity behaviour in crystalline LiF and MgO matrices under the action of radiation

Abstract

Abstract The comparative analysis of the results obtained in the investigation of infrared absorption spectra of irradiated lithium fluoride and magnesium oxide samples has been made. For irradiation of the samples X‐ray generator, Co 60 source and different reactors were used. The universal linear dependence of bands caused by centers containing OH – ions was observed for the first time in the irradiated MgO samples. The thermal treatment of irradiated LiF crystals have clearly showed the interconnection of hydroxyl ions and hydrogen products of their dissociation.The significant difference in the behaviour of impurity hydroxyl ions in matrices of the mentioned ionic compounds was observed.
