Influence of copper ions on recombinational processes in KDP

Abstract

It is investigated ТL of the crystals KDP doped by cooper ions. The cooper ions occupy cationic units or interstitial depending on a way of activation. It is established the Cu2+ as ions replacement and interstitial raise thermal stability of a matrix defects and give new peak ТL at 140К. The presence of replacement ions Cu2+ in a lattice KDP results in occurrence of the new TL peak with a maximum at 240К. The assumption is made, that it is connected to formation of the centres Cu+.
