In this paper, Dy3+ doped phosphors were synthesized by high temperature solid state reaction technique. The phase purity of the sample was confirmed by the X-ray diffraction (XRD) technique. Elemental analysis was analyzed by using EDX. Photoluminescence spectra reveal that under the ultraviolet (UV) excitation at 352nm, white light emitting phosphorescence originated from the mixtures of three emission...
Thermoluminescence (TL) glow, TL emission (TLE), Optical Absorption (OA) and Photoluminescence (PL) studies were made on γ-irradiated CaF 2 :Dy:Pb:Na single crystals (Dy-0.005 at%, Pb-0.188 at% and Na-0.007 at%). The TL glow curve (after 206 Gy dose) exhibited three glow peaks around 394, 445 (shoulder) and 536 K. The first peak was found most intense for lower doses (<∼3680 Gy) and beyond...
