Abstract. A few KDP (KH 2 PO 4 ) and KDP: La 3+ (LaCl 3 ) single crystals were grown
being based on the temperature reduction method. Investigations show that the presence
of three valent ions like La 3+ could be a cause of retarded growth rate and induced
crystalline lattice defects. Here the pure KDP crystals are compared with KDP: LaCl 3
before and after their exposure to gamma irradiation. Both types of crystals also were
studied in aspect of other structural and optical properties.
Keywords: KDP compounds, impurities, γ-ray effects, optical and structural properties.
