报道了一种用于X射线和γ射线探测的新型铊基本征激活闪烁体。在室温下测量了样品在X射线和γ射线激发下的发光和闪烁特性。该化合物是使用两区垂直布里奇曼法从熔体中生长的。X射线诱导发射光谱在441 nm波长处显示出强的发光带。在662 keV的137 Cs源激发下，闪烁光产额和能量分辨率分别为37,600 ± 3700 ph/MeV和4.6%（FWHM）。在室温下，用γ射线激发样品，得到了两个衰减时间常数。测量的性质表明，该化合物是一种潜在的闪烁体，可用作辐射探测器在不同的应用。
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 from137Cs 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.
