Scintillating optical fibers containing non-uniformly distributed dopants and process for preparing same

摘要

Scintillating fibers are provided comprising an outer layer, an inner layer, a fiber center and an interface between the inner and outer layers. The distance between the fiber center and any point of the interface in a fiber cross section defines a radius and the distance between the fiber center and any point located along the radius defines a fractional radius. The outer layer has an index of refraction lower than that of the inner layer. The inner layer contains a dopant non-uniformly distributed within the inner layer. Processes for the preparation of such scintillating fibers are also disclosed.
