Study on the defects of KDP crystal with different states by the positron spectroscopy method

Abstract

KDP and ADP crystals doped with different concentrations of Fe3+ ions were grown by the “point seed” technique and some KDP crystal samples were annealed. Positron annihilation lifetime spectroscopy...

Study on defects during Fe3+ doping and annealing in ADP crystals

“…The results indicate that as the concentration of Fe ions in the growth solution increases, the content of iron in the ADP crystals also shows a noticeable upward trend. Unlike the case with KDP crystals, 27 in ADP crystals, the iron content is consistently higher in the pyramidal (PY) region than in the prismatic (PR) region. This suggests that the structure of ADP crystals may facilitate doping more readily in specific crystallographic directions.…”
