Abstract

New thallium based intrinsically activated scintillator for X-ray and gamma ray detection is reported. Luminescence and scintillation properties are measured under X-ray and γ-ray excitation sources at room temperature. This compound is grown from the melt using two zones vertical Bridgman method. X-ray induced emission spectrum exhibits intense luminescence band at 441 nm wavelength. Scintillation light yield and energy resolution are found to be 37,600 ± 3700 ph/MeV and 4.6% (FWHM), respectively under 662 keV excitation from ¹³⁷Cs source. Two decay time constants are obtained when sample is excited by γ-ray at room temperature. Measured properties revealed that this compound is a potential scintillator and could be used as radiation detector in different applications.
