Paper Abstract

This report summarizes an investigation of new luminescent glasses for use as x-ray-tolight conversion imaging media for x-ray radiographic applications. Luminescent activators such as T b3+ Eu2+ and Ce3+ were investigated in high density 3 g/cm3) high z fluoroborate fluoride borate and silicate host glasses. Terbium activation in each of these materials has at least a factor of 2 higher luminescent response under x-rays than either of the other two activators. The selection of the host material has a large effect on the luminescence characteristics. Terbium activated silicate glasses have a luminescent response 3 times higher than any of the other terbium activated glass materials investigated. The addition of Gd3 to terbium activated silicate glass has been shown to improve the x-ray-to-light conversion efficiency by as much as a factor of 1. 2 for this glass material. This increase in efficiency most likely occurs because of a Gd3+ Tb3 energy transfer process. 1.
