Abstract

Single crystal of KCl doped with $Eu^{2+}$ ions was grown by the Czochralski method in the high pressure Ar gas(purity 99.999 %) atmosphere with chamber pressure from which the crystal with high quality was obtained. As grown $KCl:Eu^{2+}$ crystal was checked by X-ray diffraction. Luminescence properties of KCl:Eu are investigated by laser-excitation spectroscopy under 355 nm excitation at 14 and 295 K. The broad emission band due to the $Eu^{2+}$ 5d $\rightarrow$ 4f transition is peaked at 417 nm with full width at half maximum of about 20 and 30 nm.
