Study on the application of scintillation screen of Gd2O2S:Tb, F / gel glass in the X-ray imaging

The transparency of scintillator screen has always been an important factor restricting the imaging performance. Here we present an innovative strategy, by combining the gel glass with GOS:Tb, F, we fabricated GOS:Tb, F/gel glass scintillation screen for effectively improvement of transmittance. The transmittance of the scintillator screen is ≥ 55% in the visible region. Thereafter, the relationship between the luminescence properties of the scintillator screen and the X-ray voltage and current is discussed in detail. In addition, the resolution of the scintillator screen under X-ray is 10 lp/mm, which may provide a promising application strategy in X-ray imaging.
