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

Abstract

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.
