Radiation Defects Formation in Lithium Fluoride Nanocrystals and Crystals in Atmospheric Pressure Glow Discharge
Abstract
Lithium fluoride nanocrystals and crystals were placed on an anode of atmospheric pressure glow discharge and exposed to the discharge components. After exposure the photoluminescence of the studied samples was measured. Based on the luminescence spectra, it was found that in unannealed nanocrystals after exposure to a discharge, color centers with new properties inherent to near-cluster centers are formed, and upon annealing of nanocrystals, the conditions necessary for the formation of near-cluster centers are eliminated. It has been found that when annealed nanocrystals are exposed to a discharge, these necessary conditions are partially restored, that opens up new possibilities for elucidating the processes and mechanisms of the formation of centers with new properties.
