چکیده

Abstract Eu:CaAl 2 O 4 , Eu:SrAl and Eu:BaAl crystals with various dopant concentration were synthesized by the optical floating zone method, photoluminescence, scintillation, afterglow properties investigated. Under X-ray irradiation, exhibit a broad emission band at 440, 520, 500 nm due to 5d-4f transitions of Eu 2+ respectively. The decay time constants are consistent typical values . Photoluminescence quantum yield scintillation light evaluated, each property was compared comprehensively understand characteristics.

Growth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics

In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...

The Effect of Annealing, Synthesis Temperature and Structure on Photoluminescence Properties of Eu-Doped ZnO Nanorods

In this study un-doped and Eu-doped ZnO nanorods and microrads were fabricated by Chemical Vapor Deposition (CVD) method. The effects of annealing, synthesis temperature and structure on structural and photoluminescence properties of Eu-doped ZnO samples were studied in detail. Prepared samples were characterized using X-Ray diffraction (XRD), scanning electron microscopy (SEM), particle size a...

A Review on Luminescence properties in Eu Doped Phosphate Phosphors

In 1996, Matsuzawa et al. reported on the enormously long-lasting afterglow of SrAl2O4: Eu 2+ co-doped with Dy ions, which was more than 10-times brighter than the previously widely used ZnS: Cu. Since then, research for stable and efficient phosphors has constantly gained attractiveness. However, even today almost 15 years after the invention of SrAl2O4: Eu 2+ the number of luminescent materia...
