Description
Summary:In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The XRD, EDX and SEM results confirmed the formation of KCl compound. The UV excitation, X and gamma rays were employed to evaluate the scintillation and optical properties of the synthesized samples. The X-ray induced luminescence spectrum of doped crystal showed the prominent blue emission at 400-460 nm wavelength region. Also, the thermoluminescence response of doped sample showed a strong TL glow peak at 200 and proper linear ranges as a function of dose making it a promising candidate for dosimetry and photonic applications.
